You can move within your country and your experience will be entirely different. You can’t in China, because it’s an authoritarian hellstate.
I agree that Republicans are authoritarians, and that sucks. I also acknowledge that you likely view hierarchies as inherently authoritarian and that we’ll likely not see eye to eye on where to draw lines. Also fine - that’s what liberal ideologies want, is that disagreement.
But to compare China positively with the US in terms of authoritarianism is, frankly, a bit silly.
Unironically the answer is “shop less.”
Prices on goods rise when demand for goods stays sufficient to support the price going up. The less everyone buys, the less things will cost.
Prices for goods have almost nothing to do with the price of rent, but the mechanisms there are the same - it’s just that you have to encourage building rather than “live somewhere less” because the second option really isn’t tenable, for obvious reasons.
If you want rent to come down, campaign for, vote for, or even run for office to be the candidate that will change zoning laws and encourage building multifamily housing.
