That would only be true if the US allowed only the same number of immigrants from each country. I don't think that's been the policy historically. I'm not familiar with the current policy. People immigrate for different reasons at different times. The causes combine with changing US immigration policies and the dynamics of preferential attachment to diaspora clusters to create distinct cohorts that have similar socioeconomic outcomes.
