Yes it is, but liberals don't think of it like that. For them the homelessness is the outcome of personal choices meaning that even those that genuinly pity the homeless people will still consider them as victims of their own vices instead of the system that engineered the entire problem as part of the class war they probably hear about but refuse to consider.

They also probably heard and maybe even believe that the socialist states got rid of the problem, but again, never think it's because under socialism homelessness is not a class domination enforcement tool but a logistic problem. For them it's because the homeless were forced (again, libs think a lot of the homelessness is voluntary) to live in barrack, psychiatric hospital, prison, gulag etc. etc. A price for having freedoms especially that a lib will never think they will have to pay that price someday, right? They are not gamblers/drunks/junkies etc, right?

Housing people is also a taboo topic because of how libs approach to concept of welfare in general, if the lib struggle to pay the rent and has no hope of ever buying their own home, how in the hell can anyone from "undeserving self-inflicted" pariah group just recive one?
