Funny you mentioned Wal-Mart because they've already been providing support to an effective housing solution in the form of letting RVs stay in their parking lot.
I've come across many people that this type of housing seems to work quite well for. Of course, I wonder what might be the repercussions? Might require some oversight to prevent devolving into tent cities? But then again, I'm not personally aware of tent cities causing much harm (to anyone outside of the tent city)
An RV is better than nothing but they are not built for continuous use. An RV that is being lived in full time will start falling apart in a few years.
that has zero realistic chance of happening in the US. Even repealing the Faircloth amendment that limits public housing stock is not broadly popular.
And these days all housing providers, whether for-profit, non-profit, or public, are running into the same issues with zoning, financing, rising costs, etc.
