I feel like a better comparison would be AC vs good quality house design, where we aren't so reliant on AC. AC would still be necessary for some people in some climates, but I know my rental in Australia isn't designed to withstand heat at all, compared to a rental I had in Germany. It's putting an expensive bandaid on something that ought to be fixed in the design stage. Edit: For context I'm referring to "cheaper/better/faster production" having a negative impact of the quality of housing, which disproportionately impacts renters, who don't have the ability to improve their rented dwelling. Regulation is the only thing that will improve the housing situation for those born too late to buy in the current market.
