I think economists would call that a feature and not a bug. It is essentially an auction (something economists LOVE). You could instead take that money that you're spending on surveillance and instead spend it on giving the contractors a bonus to show up to your place instead.

I really don't buy that this would "shame" them into coming to your place first. Everyone already is aware that they don't always show up because you got out bid. You're "solving" the problem the wrong way because you're not addressing the actual problem.

I would imagine shaming doesn't work because I think residential GCs have higher demand for workers than there is supply, but the cameras still solve the problems of making it easier for the GC to react when it happens (and the reaction could be offer to pay that sub more if the project is late or all the other subs have been showing up, realizing the work from the earlier stage wasn't done, and going home, or it could be lengthening their project schedule).

Perhaps the GCs are unaware of the surveillance themselves
