Yeah, no. This is incredibly insulting.
I am not incapable of helping myself. I am working damn hard every single day to resolve my problems in the face of a hugely uphill battle that is compounded by sexism, housing designed solely for the rich and a whole bunch of other entrenched barriers to ordinary people making their lives work.
You may be able to pretend that the homeless (and other poor people) are a bunch of utter and complete losers who can't help themselves, but your reply means you either didn't really listen or didn't really understand.
As these problems deepen, larger numbers of people are being pushed out into the streets. Perhaps if homelessness hits 50%, the world will stop talking like it is merely a bunch of fringe losers who need our compassion and charity and realize that, no, actually, the system is deeply broken and actively screwing over a very high percentage of people and chewing them up and spitting them out.
Or perhaps all the rich assholes will continue to be all LA LA LA NOT LISTENING, you must just be defective as it cannot possibly be the shitty company/policies I created that is somehow at fault.
