There is actually a super simple solution to this: Have the government buy up a ton of properties and then rent them out to people at reasonable rates. A little bit of it is enough to pierce the bubble and bring rents down, and it generates revenue for the government, and people start investing in productive businesses instead of in properties. Literally everyone on all sides wins, except your landlord.
We could have been working on that, but it turned out it was super important for Hilary to win the primary, and so what the fuck here we are.
