The same issue as drug enforcement arises - how does it stay a profit center when those you punish are those that fund your election? It may be a profit center for the vault of the State, but it is very much not so for pockets of the campaigns. The reason why wage theft is inexplicably and reliably the biggest and yet the most overlooked shape of theft seems to me to be that one.
Labor law enforcement could be run as a profit center, like drug enforcement, if the fines were higher.
