Honestly, I have no idea. However, that is the kind of person he would need to be to get a 3 hour a day programming job. Or he is full of shit and talking out of his ass but that would be uncivil so I better not say that.
Or he's a programmer with a respectable hourly rate (100+) and only works a few days a week remotely who lives in a cheap area. Any decent programmer can attain this.
