While you are correct that we need schools, parks, and other public goods, your theory falls short in the fact that over $400 billion dollars worth of donations are contributed towards the good of the public each year in the USA. Areas in the USA that need the most attention towards their school systems, justice systems, and public areas are also the same areas that contribute little to no tax dollars towards their own cities. In inner cities such as these, the percentage of welfare recipients who are not legal US citizens is upwards of 30%. It is a shame that people assimilate in poor areas but but a measly 6 % (70 billion dollars) is not worth the abuse of the other 94% of taxes.

I believe that in a free country the money belongs to the person who goes out and earns it. Those who produce a certain amount of wealth shouldn't have it taken away from them, I do agree that a certain portion of money should be set aside for things such as national defense and the justice system but the government shouldn't have their hand in my pocket for something such as welfare programs. People who are unwilling to work should not receive my tax dollars, I have no remorse for a weak individual who expects a handout. Individuals who physically cannot support themselves(i.e. Disabled people) are a completely other topic. If we want smaller government, reduce the amount of taxes that Congress has to play with. Small government was the reason why the economy was booming in the 1920s, big government was the reason why the Great Depression hit.
