Strawmen aren't helping here. "The labor of the productive" is becoming a very small set. Clearly they'll have to be motivated differently. Obviously the way forward isn't breaking the system with a hammer, so lets stop going back to that.

Incentive to live is different from incentive to work. Look at open source; look at researchers in universities. Wealth is not the motivator there, yet there's tremendous productivity coming from that.

The meaning of wealth is going to have to change.
