I have paid for many other people in my life, too. I was happy to pay for them. I am not very happy about having to pay my other dependent Paul. Many people protested the undeclared war in Vietnam during the 1960s by refusing to pay that fraction of their income tax which they computed to be used for the war. Americans have been protesting oppressive taxes ever since the Boston Tea Party.
Tax protests are even more American than apple pie.
In fact, oppressive taxes were one of the main reasons why we rebelled against Mother England. I tried this idea on a couple of close friends and got predictable results. One told me she had grown up on a poor farm and would never have been able to go to school if her dad had had to pay for her schooling. The other told me he grew up in a poor home and would never have gotten his education either. Both of these friends of mine made me feel ashamed I had suggested such a rotten idea.
