I think the premise is far more absurd than that. 'Incentive' theory evidently only applies to millionaires and billionaires, since these same theorists obviously expect any labor class to work for wages insufficient for survival. In addition, if only the incentive of profit will induce the guy that already has more wealth that he can possibly spend in a lifetime to work, isn't he essentially "working for nothing"?
Furthermore, has not something greater than 50% of all humans that have ever lived worked frantically their entire lives for nothing more than the slimmest margins of survival? The theory is patently and demonstrably absurd. 100% of all history and reality incontrovertibly prove it utterly false.
The nazis proved humans will work until they drop over dead of starvation and / or exhaustion on no more "incentive" than simply avoiding a bullet in the head... even if a bullet in the head is ultimately inevitable. Humans will work for nothing more than the promise of a bullet in the head tomorrow if the only alternative is a bullet in the head today. Place those billionaires in a nazi slave labor / death camp and I guarantee you not so many as one of them ever refuses to work.
In addition to mere survival for the next five minutes, add an education, a safe and comfortable home, health care, a steady supply of food, a constructive participatory role in society and a comfortable retirement, and you can induce a human to do just about anything you can imagine. Billions or even arguably millions of dollars is not 'incentive' to work. Survival is incentive to work, comfort and contentment are powerful incentives to work.
The "incentive" to accumulate wealth too great to spend in a lifetime is psychological impairment, and we don't need to worry about incentivizing that, we need to worry about deincentivizing it.
They are right in a way. People who make such claims are usually lazy ba$tards themselves that will not work in any society. So yeah, under communism, we will have to work to feed these few a$$holes and pay their rehab charges.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
