Like I said, critical thinking is tough for some folks. The only way anyone would trade places with desperately poor uneducated immigrants without hope, money, education or advanced skills is if they are in the same boat. The law of supply and demand you mentioned should be put to a test soon now that Trump is deporting all the immigrants. Get ready to hear about rotten crops. Or expect to pay a lot more for everything, take your pick.

yes wages will be going up and the inequality Democrats oppose so much will be declining thanks to Trump.
