Two things: capitalists don't not work; and if you have a sizeable portfolio, you may not need to work and may earn plenty of passive income, yet still work because you add more value at the margin working than fiddling with stock allocations or angel investing or whatnot (vs index funds etc.).
It's easy to get a capitalist to come out of retirement. Most of the time you just have to ask them to take a look at your business. Before you know it they accept a board position and shortly thereafter they are running point as President.
