Serious question about immigration & the economy

[guillaumeb]

1. Yes it would mean that.

But if one economy has literally no opportunities for all of its workers, the contribution of the unemployed is not a factor.

One example:

After NAFTA was passed, US produced and subsidized corn was cheaper in Mexico than Mexican corn. So many Mexican farmers left to find farm work in the US. This had the effect of destroying the ability of these farmers to work in Mexico as well as allowing US farmers to hire these workers at lower wages than they would pay to a US worker.
