Here, where he says open borders are harmful to ordinary Americans' wages.
Why is it the only prominent politician who really truly gets it is the socialist Bernie Sanders? Donald Trump, by contrast, has claimed American wages are too high and does not support increases to the minimum wage.
Maybe Bernie's not really a socialist as he claims. True socialists welcome free trade and open borders because they know that equalizing wages globally will hasten the revolution of the proletariat since it widens the gap between rich and poor to the extreme, driving wages down in a race to the bottom, ending in a violent overthrow of the rich capitalist owners.
Instead Bernie believes in the US nation state. If he's a socialist, he's a national socialist. He just can't say it. Instead he calls himself a democratic socialist.
