In a time where company profits are higher than ever before and worker wages are remaining stagnant, I think it's a valid concern to raise. We do live in the richest country in the world, after all. Why shouldn't everyone living in it prosper?
Also, I was born and raised in America, and I am not responsible for the transgressions of my ancestors. I also don't blame the foreigners that try to come here; I blame the government and corporations that are making a system that only works for the richest of Americans.
