Like the housing projects in the inner cities?
The problem with US housing projects isn’t that they are social housing but that they are deliberate concentration of the poor (and therefore also marginalized, as those are correlated), with the same consequences that always has, whether or not it involves social housing.
AFAIK those planning such projects did not themselves live in social housing (unlike, say, many soviet officials), hence there's still an element of hypocrisy there (note that I never claimed otherwise; I specifically chose the word "this" in the sentence you've quoted. I'll also re-re-state that I've not made any argument for or against home ownership or renting)
See here, for example: https://en.wikipedia.org/wiki/Subsidized_housing_in_the_Unit...
Heh, I wasn't taking a position on renting versus ownership. I said there are pros and cons of both.
What is unjust is to advocate for renting, if that rent will go to an owner/landlord. After all, why should owners/landlords exist at all, if renting is apparently so good?
Social housing avoids this hypocrisy, since the "owner" is not a person (or person-surrogate, like a corporation).
