You could just do what you do now, but after removing all the bullshit PR, Banking, Marketing and PMC jobs, there's double the workforce so the plumbers work 50% and are happy because they have more time to work out and hang out with friends and family.

Alternatively: we repurpose "self-driving" Tesla busses, put in a bunch of sleep pods and turn them into mobile automated gulags on wheels. They just drive up and unload a crew of former PMCs/CEOs led in at gunpoint by AI robodog, restrained by shock-collar, that amazon gadget registering if you're moving or not and geo-fencing as they are forced to scrub that bowl, fix that leak, paint that wall and so on. They get re-educated in VR (that detects if your eye-lids are closed or not) as they are transported between worksites and sustain themselves on a steady diet of soylent meal-replacement. The busses are parked on a repurposed luxury liner just circling the globe picking them up and unloading them to disaster sites as needed. Trapped in a high-tech torment nexus of their own creation until they repent, after which they get a small apartment and a bicycle in some really small town where they can never hurt anyone again. Fully automated so no camp guards are needed or hurt.
