I have a problem with this part: "Given a choice between a part-time or easy job paying $60,000 and a demanding, stress-ridden job paying $120,000, Lederman would be wise to take the former" So, people making 60k a year have either part-time or "easy jobs" and those making 120k are working hard and contributing to the economy, right?
