It may look like some corporations try to reach that goal but I think governments generally tend towards a goal of 96% employment.
Well, I would go for national banks perhaps since they're meant to be sort of...national.
The problem is that the problem is global and if the solution is done wrong then the corporations can either migrate, blackmail or just increase prices by a whole lot which will lead some of them to fail as they cannot get customers any more due to limited purchasing power. What you want is a solution that stops the wealth distribution from constantly going upwards and IMO this starts with a distribution of investments because those are IMO largely responsible for the upwards stream as poor people cannot invest and wealthy people only invest if it increases their wealth. The least that cut happen is that poor people get a cut of that investment-pie.
