Being poor myself in a first world country, everyone hates you - not just the government. People cross the street because they don't want to interact with you. Family members shun and ignore you, because they are worried that you may ask them for money. People question your mental capacity and sanity. People that are better off, use you as a springboard to boost their own ego's rather than trying to help you. Lets be real, everyone who isn't homeless at one point or another has engaged in downward social comparisons.
Friends disappear - no one wants to associate with a homeless person. People refuse to give you work, they just want you gone.
