Kill jobs in the sense that wage suppression drives the American worker out of that market. Flooding immigration is wage suppression. Add to that the cost of subsidies in the form of welfare.Immigrants (legal or otherwise) don't "kill" jobs. They 'take' jobs. And in this case it's arguable that immigrants are actually creating jobs for people who are protesting over part of the reason that they actually have a job to go to.
And all ultimately paid for with taxes.
Very much like a perpetual motion machine. It works fantastic until laws of thermodynamics grind it to a halt. Except in this case, laws of economics and common sense prevail.
And meanwhile, these people are protesting a situation that benefits their employer which benefits them (the protesters) by having a job to go to?
I'm going to put my bias aside and ponder the possibility that there MUST be pieces of the story missing and that these people aren't as unfathomably stupid as I think they are.
And that the protesters will put their money where their mouths are at by donating their wages of oppression towards improving the plight of the immigrants they so obviously care sooo much about.
