Tax isn't charity. It isn't something you give out of the goodness of your heart. Its the bill for all the many services you enjoy, whether you're rich, or poor. If you disagree, spend a week using literally zero government provided services, and then talk.

The idea that giving to charity is enough to improve humanity is fundamentally idiotic. Large scale issues, whether it is government funding of medical research, or food inspections, or validating drugs, simply cannot be solved by charitable giving. Nor can you be charged per service, since the ripple effects of these kinds of service mean pretty much everyone benefits.

Americans like you just aren't aware of the efficiencies and advantages they gain from even their imperfect and less than completely efficient government. You've taken so many aspects of your life for granted that you are, it appears, completely unaware that, constantly obstructed as the American welfare system is by nitwits like you, there is still a trickle of services that barely manage to maintain reasonable stability.

Next time you feel the urge to claim that your charitable giving is somehow supposed to substitute for taxes, I urge you to try that tactic with Amazon, or Walmart. Ask them if you'll be given the stuff you want from their stores in exchange for maybe giving donations to their workers.
