maybe because some dont support theft. others see that HUD housing sucks, that food stamps dont buy the best food, and that they cant get better. or that even if govt services could get better, they would run out because less can be produced the more that is consumed.
even more people can see that the Democrats, at least many of the well connected ones, often dont like to pay for others but they like to redist on the backs of the productive. congress doesnt care about us because they vote to steal for themselves. congress isnt that smart so even if they did care about us they wouldnt know how to (newt gingrich pointed out that congress isnt that smart). obama is smart but he is concerned only with saving his life from the cia. look at how much more mitt romney and ron paul gave away of their own money than obama gave away of his own. look at how much more obama has taken than ron paul did. look at how much more of ron paul's own money and services he was willing to give away and how much more he didnt take from others than his son has given and not taken from others.
others who arent rich but who work very hard dont like being stolen from.
some people dont want to see more stagnation which is what happens when more people are consuming food stamps instead of being able to make investments in resources that would allow production. in other words, everyone consuming a minimum of $4k worth of goods and services plus State services and materials each month with 1/3 producing nothing is not possible
finally, it is not real charity if people are being forced to do it.
