You can't fix political bias with more political bias.
The central problem isn't rent control, it's the fact that property is a very privileged asset class that allows owners to extract rent from those with less political and economic power.
Rent control is like pushing down on a balloon that's inflating. The inflation keeps happening whether you like it or not. The best you can do is minimise the effects in selected locations.
That doesn't mean rent control is causing the problems. The underlying problem is the inflation, and you can't make it go away with palliative measures.
In the US, you can't make it go away at all, because the economic system has been designed to privilege rent-seeking - at various levels of obviousness and abstraction - over other kinds of activity.
Rents in the Bay Area and the financial biases and traditions of VC and startup culture are both manifestations of the same underlying problem.
