Not in the US. Occasionally, some effort to make a homeless camp livable is talked about but the powers-that-be still act to do the opposite, first the make homeless camp a hellhole and then kick everyone out to re-appear elsewhere.
Isn't a livable homeless camp a shanty town? Is that really something to aim for as the long term solution? Personally, I like the freedom it gives residents but it also gives them health and safety problems and people are generally awful at protecting themselves from that.
