Holy crap, the amount of socio-economical hate in this thread...

People don't hate the homeless, they feel guilty and the best way to deal with something that makes you feel bad is to reject them, for example let's say you buy something you really wanted in Christmas, and you see a homeless person, but you don't have more money to help them, you aren't going to change the thing you bought back to help them, but instead you'll ignore them because it is a situation that is unfair to both of you, you did earn the money you spent and you are not to blame for using it, but on the other side the homeless, well most of them, aren't at blame for the situation that they are in.

This also gets worse with time because of the desperation the homeless rightfully feel and how they express them.

And this is also something very USA centric, the country has so much social issues that it's mind blowing to an outsider, you can better see this when immigrants get to the USA, somehow, they manage to get in a better foot than normal citizens while having less access to support systems.
