Where do you come up with this racist crap? As someone who grew up in a poor white area in the North of the US I can assure you that race has absolutely nothing to do with lack of low-paying jobs concern.
>Of course, there is no reason why these people should make close to nothing while other people throughout the economy have bullshit jobs that pay really well.
Supply and demand. It's economics 101. It's like claiming that there is no reason people should be paying over a thousand dollars for an ounce of gold when copper is only a couple of dollars a pound.
If the people with low paying jobs were qualified to do the higher paying job, the employer would happily hire them for a lower price to save money.
This is especially true because if you don't work, you'll almost certainly be homeless, hungry, ect so the entire premise of there being a fair market for labor is false.
