How are the non-rich paying all the taxes when at least half get a refund?

Often even here in Fluther I hear how the top 5% are riding off the backs and labor of the middle class. How is that when it seems that half are getting a refund? Listening to H&R Block, Hewlett Jackson, TaxAct.com, Turbo Tax and the likes a whole lot of people are getting refunds and they swear they can get you the most money back. If you overpaid your tax you get the overpayment back so how could the middle class be paying more than their share? Just because the wealthy has more tools and ways to use the deduction anyone who qualifies can use don’t mean they shouldn’t use them. The poor do not pay taxes at all but enjoy all the trapping of them. Would you say the poor is riding off the backs of the middle class and wealthy?
