There is no feasible, affordable way to export all of our illegals....it's an unattainable pipe dream....especially with constant war at our door step, a national debt reaching Heaven in a hellish way, and still running deficits and adding to the debt, with no one in congress willing to raise taxes and cut spending to pay down our deficits and debts.
We have to prioritize on who gets arrested and sent back to their country of origin first, then second, then thrid etc and some WILL have to stay here, just due to the legal ramifications and prolonged court hearings and law suits with sending parents of American Citizen children home.
Also, maybe 20 to 25% of Blacks are poor, the rest are already middle class or higher, holding jobs way above the illegal immigrant level, for the most part...
I agree it would help the unskilled workers the most, no matter their race, if all the undocumented were rounded up and sent home, without costing us a fortune to do it...
However, a mere President can do nothing that Trump wants to do, it would take immigration reform that congress is not willing to make....so Trump is just using his rhetoric to rile the troops, but it's meaningless, unless Congress backs him and funds it, at the expense of something else cut.
