Well, it's pretty hard to generalize that to the entire globe, or universe. Imagine if an alien race started landing thousands of crates on Earth full of cars, computers, clothes, etc. Every day for 30 years the crates come, all of it's free. Several dynamics can arise:

1. The elites grab the crates and hoard them, leveraging their existing power to make sure they enrich themselves and extend their power. They sell the items, but at a lower price than the Earthly-produced items, which is easy since they have 100% margin.

2. Whether or not #1 happens, it becomes impractical to make any of these goods for a living, so people stop. Eventually, the factories are dismantled or simply crumble.

Now Earth is dependent on the aliens to keep sending the crates. If the aliens ever get wiped out, or just elect a populist who doesn't like to give aid to inferior planets, then we won't have any cars, or clothes, or computers.

We don't even need to bring aliens into this scenario - as this is the direction we are already heading towards with fully automated manufacturing and AI replacing vast sectors of human labour...

(And yeah, I get it - no one "really" wants to work on a "soul-crushing" assembly/production-line... People want to make art (or games) or write novels... (both areas of creative work which are ALSO being targeted by AI)... but people definitely want to "eat" and have shelter and our whole system is built on having to pay for those priviledges...)

Or people do other things.

Around 1800, 95% of people worked on the farm. Today it is 2%. People do different things now.
