From what I can tell, most of the hate directed toward Kamala Harris over “price controls1” is actually because she wants to streamline permitting and smack down NIMBYs, thus making housing easier to build.
The NIMBYs are doing all they can to fabricate whatever petty calumnies they can to make sure this doesn’t happen. For many, their entire politics is based on the price of their house and nothing else. That’s a lot of what we’re seeing now.
