I think every able person should contribute, and when people don’t, it’s probably because they’re suffering from mental illness, probably depression. I’m sorry for those people, and I see no reason to force them to work.
And yes, the robber barons are parasites who feed upon the labor of everyone else. I’m far more concerned about how they’re harming society than some poor guy who struggles to get his shit together, and is mostly harming himself. How about some psychological/psychiatric help for that guy?
