I grew up in poverty and faced homelessness many times, and my experience anytime a public/government program was offered to help people like me specifically, it only made things worse, either directly or indirectly. Every single time.
Extra policing meant more poor people pulled over in their raggedy cars and ticketed for vain things. Food assistance meant lots of forms being filled out, and the risk that your inconsistent income might go just above the threshold next month and kick you off for the whole year when your income drops immediately thereafter. Healthcare assistance meant even more forms, confusing jargon, and always started with "don't worry, we'll take care of it" and ended with "you now owe $5000". I could write posts full of examples.
Even worse, once I identified this, I could then be labeled "too stupid to know what was best for me" or "just sticking up for the rich" when I expressed my concern for this around (mostly more privileged) friends.
Naturally I tend toward libertarian hands-off opinions on things like this now as a result, but not because I don't think food assistance or satiation of basic healthcare needs could be helpful. Quite the contrary, they could make a huge difference if done in the right balance and the right way.
But given the realities of how these things work, and have worked my entire life, the institutions creating and promoting these things are either incompetent or corrupt, or both. If all of these caring researchers and think tanks put more effort into retrospectively finding out what is going wrong with these programs as they exist today, and found a way to restore competence and trust to the programs and the institutions behind them -- if everyone could be honest about the actual results of their efforts rather than just patting themselves on the back for doing what felt good while ignoring the people they caused to suffer -- then I'd likely feel differently.
It makes me wonder if my problem growing up weren't the supposed "safety nets" that blew up in my face each time, but rather the institutions behind them, and that they should be the first problem solved before we move on to the assistance itself.
