Often racists make themselves believe that non-whites somehow has easier access to welfare than whites and gets angry about it.

An example of this from my country is an urban legend that has circulated for almost half a century about how you know someone whose cousin has a colleague who knows a guy who works on constructing a completely new housing block in another city with all modern luxuries, and how only refugees and asylum seekers will be allowed to live there while whites have to stay on the normal waiting list for social housing. The story is complete bollocks but it illustrates the racist anger that somehow non-whites are coming here and taking our stuff.
