People in comfortable positions wish that other people would stop competing to take them away.
Organizing the whole world to stop competing only sounds nice when you imagine that it means you get to lock your position in life in place and stop feeling threatened.
It becomes much less attractive to most when you look at what it would actually mean to stop competing and have everyone revert to the average. Global average income is around $10K per person. If you make more than that, you’d have to give up a lot. That’s not even accounting for the sharp drop in production of things you need that would happen if the upsides of working hard were removed, leading to people working less.
A transition away from competition could also be implemented by capping the standard of living to what it currently is in the richest countries and then waiting for others to catch up. After that production would slow down yes, and that's the point. People could spend more of their time on things that really matter to them instead of things they're forced to do by competition.
