Why are there 300 applicants? Why do employers have high standards for low skill jobs? It's because all these people failed to get an education that prepares them for a well paying job and now the employer is basically benefiting from their choice of education without having to fund it or pay a good wage.

As it is right now, being an average human in a developed country doesn't pay because there are lots of average humans in developing countries who are begging for work harder than you do.
