Um, Vinth... since you said you are barely living above the poverty line, and since you live in/around St. Louis, AND since you are a family unit of 1, that means you're just barely making over $8980.
To be fair, I will assume that you are making closer to $10K, since you said you are above that poverty line...
I thought that you had a good job at a private school, you minimum wage making pansy. Hell, I make more than you and that's taking into account the exchange rate.
Why aren't you out there struggling to better yourself instead of whining about where your taxes go?
