India has 130 million college graduates, and 70% of H1bs. Mexico, Brazil, and Colombia together have over 50 million graduates, but only around 2% of H1bs combined.
The point is that it strongly suggests the system is being abused by India. Even excluding developed countries where people might lack incentive to move, India doesn’t come close to having 70% of “the talent.” Latin America alone probably has as many college graduates as India, accounting for higher college attendance rates. But Latin America accounts for a small share of H1bs while India accounts for 70%.
