It's at best short sighted but more likely simply uninformed to think that people with baggy pants, hats on backward and cans of spray paint in their hand can't speak proper English. I'm failing to see how one's fashion sense has a bearing on their diction or grammar. You have some stereotyping issues you might want to consider.
Perhaps the current American model taxes the middle class unfairly, but an income tax would be taxing the poor disproportionally as everybody must spend the a certain amount of money each year on essentials and if you make less, that amount is a larger percentage of your total income. Food costs money, that may or may not be 100% of your income.
Never make anything simple and efficient when a way can be found to make it complex and wonderful.
