The warm house expectation has happened in my lifetime, as has the expectation of car ownership.
We didn't have a car until I started work. We didn't have a fridge until the 70's. Frost on the insides of windows, bedding damp with condensation and drinking water iced over on the window sill was the norm.
We have friends now who wear fleeces indoors and sit watching TV under a duvet. This will only get worse.
