Bullshit / Pointless jobs ? Most are definitely not physically demanding. Meanwhile, our devices run on metals mined by 12 year old kids.
Toxic bosses ? They probably don't act in the open. And they don't pay well.
Lack of workplace regulation ? Your continent democratically decided that workplace regulations were bad, so it should be a "gleeful" metaphor ?
Bad job market ? Then the guy would be accepting a job where he gets punched AND badly paid. But that's not metaphorical: that's a lot of real life jobs.
So I'm missing something here.
