If they find a way to make money without needing to build up the discipline through a job etc., then that's great. People can do that over the internet on low-cost areas or with some familial support.

Not everyone can.

Yes, there's enough resources in the world to go around where people shouldn't have to work, let alone 40h a week.

But currently, that's impossible in every country that I'm familiar with.

I never bring this up to them, that would be assholish in my opinion.

Or they're counting on mom and dad's money until the parents pass away. Could be in denial about how much time they have and how easy it would be to get a job when that time comes.
