Wealth isn’t zero sum, it’s created all the time (and at a rate literally not achievable simply by underpaying employees, to pre-refute the expected response).

Explain. In a very basic sense wealth is created by acquiring resources (some of which are finite), then adding value through labor. So, the way I see it, the workers are creating the wealth, then the business/owners/investors/shareholders take a significant portion of the employees’ surplus value of labor. I.e. there is a pie of value/wealth that an employee creates, and the more of that pie the business/owners/investors/shareholders get, the less the workers/wealth-creators get.
