No one is forcing them to retire, I for one would be interested to see what these productive people would come up with when they shift their goal from making a great profit to making a great social impact.
I'd be willing to bet that at least some of them would. Instinctively I would also guess that it would lead to a better outcome on average, but as I'm less certain about that which is why I would like to see it tested out.
True, though I do think great profit is not possible with _maximal_ social impact (unless hoarding cash serves to restrict total consumption and thus limit climate impact).

who says they will shift?
