We know it happens constantly that a company sacks workers and has record profits. I feel like a huge number of the problems associated with capitalism come from the total lack of any incentive to do anything with profit other than keep it.
For instance, take a company like a website. What they're “supposed” to do (according to some business theory) is, once turning a profit, reinvest that profit back into the company. Make a million dollars, so hire ten new people and expand operations. What they actually do, and this scales up with business size, is fire staff and make their profits even higher, and that money goes to shareholders.
So could you have a law stopping it? Could you cap the amount of money a company can legally make and keep, this requiring them to put extra money back into the company? They'd have to raise wages and keep staff on, because if they go over a certain threshold, the excess would have to be handed over as tax.
This may be a highly impractical idea, but I've never heard anything like this floated (which may be for a reason). Could this be a thing, or is it silly?
