Can't wait till Trump is reelected and the border is finally sealed up. That would be both borders, the USA-Mexico and the southern Mexican border. Can't afford to lose all those prime arable lands to what I sadly dare say would be equivalent to a cockroach pest invasion.
For the love of all that is good. If you got the energy to march and bus for over a 1000 miles, you definitely got the energy to fix your own country up. Now unless you are only hustling northward because USA provides free stuff, free healthcare, free stuff and free gibs then why exactly should anyone want you here?
