Eleven delivery geographies. 4.2 million employment records. Four years of series construction. The conclusion is uncomfortable for everyone who sells this model, including the people who once sold it for a living.
For three decades, labor arbitrage rested on a single assumption: somewhere, there is always cheaper labor. Across eleven delivery geographies and 4.2 million employment records, that assumption no longer survives contact with the data.
The assumption was never stated that plainly. It arrived dressed as a cost model, with a discount rate and a five-year horizon and a sensitivity table that moved two variables and held the rest still. But strip the model back and the load-bearing beam is always the same: that the wage differential which justified the move will persist long enough to pay for the move.
It has not. Median real compensation in tier-2 delivery cities rose 6.1% annually across the study window, against a modelled 2.3%. Compounded across a decade that gap inverts the business case entirely, and it is present in every geography we examined, which is to say it is structural rather than local.
Because almost nobody was looking without a position in the answer. The wage series everyone cited traced back, through three or four layers of citation, to survey instruments administered by parties who benefited from a particular reading. We built ours from national employment microdata and firm-level payroll returns. It took four years, it is tedious, and it is the only reason the finding can be defended under questioning.
Where a figure could not be traced to a primary series, it does not appear in this report.
