He talks a lot about the labor market vanishing and economy collapsing because people will have no money to spend. In that context, the implied solution is to get to a point where you earn your money from property, physical or intellectual or else you're fucked.

What I don't get is who will pay you your fees/rent/buy property if nobody has money to spend? Whether you are offering a service by selling your time or some property for rent, you compete in the same market for the same amount of money available in it. What decides whether you will earn is the value of your offering for people, not the type of offering.

In my view the safest way to ensure wellbeing is to be able to produce what you need and know people who you can trade with for the stuff you can't produce yourself.
