It's possible he's not being lazy but instead is depressed. When I was let go 3 years ago at a job there wasn't much available in the area. I'd go apply at three places and come home and play video games for 6 hours straight. Then I would eat something and continue the trend all the while my wife is at work. It was wrong, but it was a coping mechanism as I was so ashamed I couldn't provide, so i just shut down in "fantasy land". Maybe ask him about seeing a psych, but do it lovingly.
