This is a reason to challenge the value of jobs, not a reason to materially damage our irreplaceable environment. Social constructions must yield to material reality.

If you ate gonna waste money to create jobs you could habe a public works programm for planting trees, or have mandatory conscription and bigger military, or have government paid for education, or infrastructure, or any number of other things

None of that transfers money from rich countries to poor countries.

Planting trees does. Indirectly by combatting climate change, which has proportionally negative impacts on poorer countries.

What's so great about a shitty job that destroys the world?

It puts food in your belly and lets you buy medicine.

Reminds of brave new world. The world government has to encourage consumption so that everyone has a job. People without jobs get restless, even if their needs are met.

Are you really thinking this through? You are justifying child and slave labor and exploiting other countries right now because of "Arbeit macht frei".
