I'm talking about the "not working while living off the income of other people" aspect. Because when poor people do that they're called freeloaders and welfare queens.
Indeed, by this logic no one should be able to retire, as the primary means of doing so, using accumulated investments, exists due to others' continued work. Even social security payments are simply the current tax base funding retirees' spending.
It all depends on what you think about capitalism, which is the social theory that the key determinant of what happens to resources is who owns them
If you are OK with that then living off rent is a natural conclusion
Me, I am not "anti capitalist" (a silly identity many of my comrades have adopted) but I believe capitalism should be an economic theory that society restricts to where it is useful and away from where it is harmful
