Simon: it's all about whether it pays a decent wage.
Who gets to say what's a decent wage. It's not about "decent" wages. It's about American companies staying alive, even competitive, in a global economy. That's why companies who stay in the U.S. have to get cheap labor from illegal immigrants. It's Adam Smith invisible hand always at work in a free market economy. American workers have to get used to the new world order or get a rude awakening. Voting for Trump got them a short break only. The invisible hand can't be contained for long.
Simon :I presume illegal immigrants don't [pay taxes]?
No good numbers on that, but many, possibly most illegal aliens pay income taxes in proportion to their low wages. They also are consumers and pay sales tax and pay property taxes through their landlords. So, the answer is many illegal aliens don't get a tax free ride.
