For warmth and necessary industry and energy, not for crap the capitalists propagandize we need or need to be jealous of. You need a home and commons(transportation of some kind for people and utilities) and food, you dont need beanie babies, pop figues, and for everyone to have their own polluting car instead of having societal investment in quality public transit almost eveyone uses. Socialists also don’t encourage replacing everything every 6 months and making things to break/planned obsolescence to encourage needless consumption.
The capitalist lifestyle is unsustainable because it relies on infinite growth on a finite world we are burning to sustain.
