If immigration laws were revamped and strictly enforced in the U.S., (all illegals deported, remove ALL incentives to stay here for illegals), the economic opportunities for the remaining U.S. citizens would be
unbelievable.
There would be a very temporary slump while all of the adjustments were made to various markets, and of course legal immigration would provide all of the labor that we would ever need, and be a lot fairer system. Plus we could control who enters the country, an indisputable right of any sovereign nation or land.
Once again, the economic opportunities for all Americans, (of every race), would be off the hook.
