When you say you are not paying Sh...t, are you talking about welfare or the answer to your question.
If you are talking about this answer, Please be assured you are getting the most accurate information availble. Information such as I am about to give you, would cost you considerably more than "sh...t" if you were dealing with the federal government website data downloads, Price waterhouse coopers, and other professional services who would charge a minimum of 75 to 150 dollar to provide this information. Check out my credentials, and you will see, you are getting a bargain. None the less, even with the risk of not being paid, I will provide you the information you desire:
The first thing I would like to say, is that when you total up the myriad details of what constitutes welfare, you will find that we pay more than 12% of our total tax dollars to welfare programs. Welfare is not a single item. It is compriesed of many progams such as food stamps, education, child care, medical care, etc.
we currently spent, $350 billion a year on 79 means-tested federal welfare programs. That's more than we spend on national defense. Theoretically, we could take that money and give $8,939 to every poor person in America, or $35,756 to a family of four.
We currently spend more than 4.4% of our gross domestic product on wellfare programs. Including state and federal government, we are spending about 22 to 45% depending on whose figures you want to go with. The Republican, Democrat, or libertarians.
