I would have to put a lot of thought into this but, it would require incentivizing those that own/run business to hire. One way to do that would be to find a way to put more money in the pockets of those that own business to hire people even when it doesn’t necessarily make sense to do so.
Essentially something like a change in 401k rules that would greatly up the amount of matching funds they could dump in their own pockets to ignore what is in the best interest of the bottom line. Create some nonsensical threshold for the percentage of revenue being used on payroll and you would probably need to put a cap on how high a person’s compensation is to be counted otherwise management would just to like congress and vote their selves a raise. This could maybe work but would more likely just bankrupt a bunch of companies and make us less competitive.
