I was reading a movie review type blog where one of the posters couldn't understand the stance of conservatives about government welfare programs. I felt compelled to write him an answer to the question he posited: " why is it evil to want to help those in need?"
"It isn't," was my reply. "It becomes evil when you use force to accomplish it, and government is force."
If I don't pay the taxes imposed on me, government agents with guns will eventually show up at my house, after a deluge of threatening letters and legal notices, and arrest me, auction off all my property and throw my family out in the street. If I resist they will kill me. That is the threat behind all your wonderful state-run charitable schemes. It behooves us then to limit, to the absolute minimum, these coercive "good works" rather then expand them.
