Discussions of why Make in India is stalling tend to converge on the same suspects: land acquisition, labor laws, bureaucracy, power costs. All real, and none of them are being dismissed here. But they read like symptoms. The disease is older than the republic. It starts in 1947, and it is fundamentally a problem of economic geography.
Manufacturing's share of Indian GDP has been stuck in the mid-teens for decades. The 25% target came and went, and by some measures the share has regressed lately. This is especially puzzling because for most of recorded history, India and China between them accounted for roughly half of the world's economic output. As recently as 1700 the two were near parity. And therein lies the difference. The India that commanded that share, and the India the British later prized as the jewel in the crown, was the subcontinent running as one system: the delta ports, the Punjab grain and cotton, the single rail grid, all of it moving as one economy. That integrated whole is what made the colony worth holding, and it is exactly what got amputated in 1947. What exists today is the remainder, and we keep grading the remainder against the achievements of the whole.
It's worth remembering 1947 was not fate. As late as 1946 a viable alternative was on the table: the Cabinet Mission Plan, a highly decentralized federation with a weak center and grouped provinces. The Muslim League accepted it. It collapsed over Congress's objections to mandatory grouping, and the collapse ran into Direct Action Day and the killings. Partition was a contingent political failure, and it fundamentally changed the economic geography available to the successor states.
Partition didn't just draw a border. It amputated the subcontinent's industrial supply chains. Take jute. Roughly three quarters of the raw acreage went to East Pakistan while almost all the mills stayed in Calcutta. Cotton was the same story in reverse, with the best long-staple crops growing in West Punjab and Sindh and the mills sitting in Bombay and Ahmedabad. The railways, built as one engineered system, became separate networks glaring at each other across customs posts. On day one, the largest jute-processing industry on earth woke up with no raw material, and the textile hubs were burning scarce forex importing cotton from Egypt and the US. A factory economy doesn't survive that kind of surgery.
But the physical cutting may have mattered less in the long run than the psychological one, which is the part most people underappreciate. The founding generation had just watched their entire economy get severed, on top of famine-scale scarcity and something like 15 million refugees. The lesson they drew was to never depend on anyone for anything. That fear reinforced the case for Nehruvian autarky, import substitution and the License Raj. Self-sufficiency beat efficiency every single time because the people in charge had lived through total supply collapse. Meanwhile Japan, then the Tigers, then China surfed the export-led industrialization wave. By the time India opened up in 1991, East Asia had already spent decades building the factories, supply chains and export capabilities India would now have to compete against. The window hadn't closed, but it had become much narrower.
Then the security bill. A united subcontinent wouldn't need a 1.4-million-strong standing army, wouldn't have fought multiple wars in its first decades, and wouldn't have felt compelled to build a nuclear triad. Every rupee that went to the military was a rupee that didn't go to ports, highways, primary schools or vocational training. Manufacturing runs on cheap logistics and a literate factory workforce, and both got starved for decades. This also explains why India leapfrogged into IT services. Software needs a fiber cable and a few elite engineers, and deepwater ports and a million semi-skilled workers are optional. The whole "services superpower" identity is best read as an adaptation to the neighborhood Partition built.
And the market shrank. South Asian intra-regional trade is still around 5% of total trade, against roughly a quarter in ASEAN and around two-thirds in the EU. A united subcontinent would be a 2-billion-person internal market today, enough domestic scale to keep almost any industry viable while it learned to export. Partition foreclosed that option before it existed.
Now zoom out, because the counterfactual is actually pretty wild. A united subcontinent stretches from the approaches of the Middle East all the way over to Southeast Asia, with the Indian Ocean sitting entirely in its backyard. And it would not have one economic center. It would have a constellation of megacities, from Karachi and Lahore in the west to Dhaka and Chittagong in the east, all sharing one customs union, one currency, and up to 2 billion consumers.
The synergies write themselves. Take Bengal. Kolkata brings heavy engineering, finance and universities. Dhaka brings one of the densest manufacturing labor markets on earth. Chittagong brings deepwater shipping pointed straight at Southeast Asia. Today an international border splits that system three ways and everybody involved runs poorer for it. Without the border, the whole delta functions as one economic ecosystem, basically a Pearl River Delta with the population of a small continent. That is the kind of cluster you cannot build with policy incentives. It just forms on its own when the map stops fighting it.
Then look west. Karachi stops being the capital of a separate country and becomes what its geography always promised, something like a hybrid of Dubai, Mumbai and Shanghai. Container terminals on the Arabian Sea, oil and LNG infrastructure plugged directly into the Indian energy market, and high-speed freight rail running inland through Lahore toward Delhi, and on past Peshawar into Afghanistan. For the first time since Partition, the subcontinent has a natural continental gateway toward Central Asia and the Middle East, instead of a fortified frontier that trade simply flows around.
And underneath all of it sits the ocean. A navy based in Karachi, Mumbai and the Bay of Bengal, with the Andamans as a forward complex overlooking the approaches to Malacca, ends up policing the entire Indian Ocean system rather than a single coastline, with Hormuz at one end and the Strait of Malacca at the other. On paper an integrated economy with that geography rivals China’s domestic market, and it can absorb global supply shocks or bankroll its own tech transitions without begging anyone. That is the version of the subcontinent that keeps Beijing up at night.
And here is the part that needs to be stated honestly, because the counterfactual reads like a fantasy otherwise. None of this requires a competent government. A united India would probably have carried most of the same flaws as the one we actually got: caste politics, regionalism, corruption, weak institutions, democratic dysfunction, glaring inequality, the occasional economically illiterate policy. Those assumptions are not being waved away. The point is that even a mediocre system running that map would have produced a richer country, because geography and synergy do part of the work on their own. The delta still functions as one ecosystem when the ministries are corrupt. A single rail grid still moves cotton to the mills when the parliament is gridlocked. A 2-billion-person market still gives industry room to learn, fail and learn again when the policies are bad. And a country with no hostile border through its middle spends less on the army almost by default. The institutions we actually got had to fight the map every step of the way. On that map, the same flawed institutions would have had the current with them. That is the real power of economic geography: it raises the floor, not just the ceiling.
So when people ask why manufacturing never hit 25%, the answer is: Partition stacked the deck, and the choices that followed compounded the disadvantage. You can't slogan your way out of that. But the number on the chart is the small part of the bill. The bigger part is the unrealized potential, the version of the last 75 years that never happened: the delta that never became a Pearl River, the gateway that never opened onto Central Asia, the rail grid that never ran as one, the generations who never left the village because the factories that should have pulled them out were never built. That is the real tyranny of geography. Not that it decides everything, but that it quietly sets the range of what policy can reach. On a good map even mediocre government lifts with the tide; on a bad map even good government rows upstream, and India has been rowing upstream since birth. Make in India and the PLI schemes are serious programs, but they are attempting, at enormous cost, to recreate advantages that a united map would have provided naturally. The mid-teens is not a mystery. It is 1947, plus compounding.
The China comparison is revealing. Strip away the Qing frontiers (Tibet, Xinjiang, Inner Mongolia, Manchuria, Qinghai) and what remains is roughly 4 million km² with a comparable population, which is basically post-Partition India. China's advantage was never just population. It retained an enormous contiguous economic space and eventually built a state capable of integrating it. India began independence with its economic geography already fractured across hostile borders. Geography didn't determine the outcomes of the two countries, but it changed the difficulty of the game each state was playing.
And geopolitically, China is the biggest unintended beneficiary of Partition, bar none.
