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.

this is not destroying things to create jobs. this is about globalization negatively affecting local culture. clothing especially represents culture. if people can not afford to create their own clothes then that has a negative effect on their culture as a whole.

Whether or not is a net loss for the planet as a whole is irrelevant. Africa countries need jobs to sustain a middle class so they no longer accept donations of clothes.
