But if you agree on the major point that the social engineering geared at getting people to live/work in one place for a long time is on the wrong track, then our differences seem focused on rent control.
I should mention that in my last building in SF there was a guy who had lived there in a rent controlled apartment since the 1970s. After the first year I lived there, a letter arrived in the mail informing me that rent would increase by exactly 1.5%, the maximum increase allowed by law, and that the landlord was pushing for "utility cost pass-through", a rent-control exception that allows slightly bigger increases in cases of utility price jumps. So I was a beneficiary of rent control.
Back to the guy. His apartment had a view of the bay and golden gate bridge from every window, including the bathroom. It could probably be rented for $3500+/month because of the amazing views. He was a wealthy lawyer, arch-enemy of the landlord and heavily involved in the tenants union, and completely not in need of any help paying rent. With rent control he was probably paying under $1000/month for his apartment and had been for years. He will probably live there until the day he dies.
I'd have been far less skeptical of rent control if there had been an immigrant family living in that apartment or someone who worked at the local Walgreens.
Why does the debate always veer back to renovation of the buildings? Do you really think that adding stainless-steel appliances to an apartment is a more desirable goal than not displacing established residents?
As for your personal experience with the wealthy lawyer, here's the balancing anecdote: I live in the Mission, a part of town where rents are rapidly increasing (I'm sure I'm guilty of driving up prices). There are plenty of people down here who can only afford to stay in their homes because of rent control, and stories of tenant intimidation are plentiful.
In the mission, I would prefer if a subsidy was just given to the poor via tax dollars. Say it's a $200 per household subsidy. Maybe it makes sense for that family to pay it to the landlord, but maybe it makes sense to find a cheaper apartment and spend it on a TV. If it turns out that the TV was the chosen decision, that helps drive down the price of rent b/c maybe the landlord will have a slightly harder time raising rent prices. If, on the other hand, the tenant chooses to allocate the money to housing, it will help drive up housing prices. The upside of driving up housing prices is that it now becomes more worthwhile for someone to convert their house into apartments, which in turn increases supply and would tend to help keep prices affordable.
Direct payment like you're advocating is a political non-starter. As paternalistic as it is, taxpayers don't like the idea that their money could be spent on anything, they want it to go only to the things they approve of.
I agree that the public would rather "force evil landlords to do x" than achieve the social goal in a minimally economically distortionary way. It similar to how politicians give handouts to people who drive hybrid cars while at the same time fighting a hugely expensive war to prevent oil prices from increasing to the point where people would just buy electric cars because they were cheaper!
