You hit it right on the head calling it an unplanned jobs program. So many jobs are unnecessary busy work (Grabers bullshit jobs) that only exist because of this insistence that people have to earn their living by sitting at a desk all day.
The reality is that the current standard of living could be maintained or even increased with many fewer people working. Or an even better standard could be reached if those people could be doing jobs that are actually useful like construction, nursing, or basic scientific research.
Unfortunately the economic system doesn’t value those things so people only do them if they’re desperate, passionate, or independently wealthy.
