BAG suggest in the comments that the US Left cares noting about working class Americans anymore. This isn’t exactly true, and to the extent that labor struggles in the US exist at all, it is the Left that supports them. And in many other ways, the US Left supports US workers politically in opposing anti-worker projects and supporting pro-worker projects at the state level.
So, the Left does support US workers, but they also advocate flooding the US with illegal aliens that have a catastrophic affect on US workers. They are also silent about the huge tidal wave of “guest workers,” – the Hindu 1-B’s and whatnot.
The problem is that the Left has a phobia about attacking immigrants. It’s not that they are plotting to destroy US workers with immigrants – though some on the Far Left do seem suspiciously like that. Mostly they just don’t care, and they find the whole conversation unseemly and racist. For the most part, they will insist that mass immigration of illegals or even guest workers has absolutely no affect whatsoever on the earnings of US workers. Then they will whip out 10 “scientific studies” that actually show that, and also show how great hordes of illegals and guest workers are for the US economy. For the most part, the Left and liberals have simply drunk the Koolaid about immigrants. They really do believe the immigrants of all kinds are the greatest thing since sliced bread.
In some ways, it seems that only workers that the Left loves in the US are the foreign workers! It’s not that the Left hates US workers. It is more that when it comes down to a conflict between US workers and foreign workers in the US, the Left will always support the foreigners and oppose the natives. This is a very anti-nationalist position and it is opposed to the interests of the Homeland. In this way, the Left is extremely unpatriotic.
But if you point out that the Left supports foreign workers over US workers, they will get mad and say that there is no conflict in the first place and you are racist for suggesting that there is. So their support for the foreigners over US workers is more unconscious than conscious. People on the Left really are goodhearted people, but too many of them have just drunk the Koolaid of various flavors and they end up promoting nasty stuff out of naivete and self-delusion that out of actual desire to do harmful things.
