The real reason is money. The goverment wants to charge for everything. You get taxed for making money. You get taxed for spending the money you were already taxed on and now if you want to help out someone in need.....lets tax that. Will this madness ever end.
Don't get me wrong I am willing to pay for what I use, but if I want to risk my life to help others in need, i shouldn't have to pay for it.
