gainfully unemployed - You have all the skills in the world, but you refuse to use

You have all the skills in the world, but you refuse to use them. You'd rather sit in a chair and watch cat videos than actually do something useful.

I can build a house, but I'd rather sit here and eat cereal for lunch.

I got a job offer, but I said no. I'm still on benefits, and I'm not even sad.

I could work, but I'd rather sleep. Benefits are like my second full-time job.
