There are definitely times when work doesn't pay:
Eighteen months after being laid off, Judith Lederman, a 50-year-old divorcee who lives in Scarsdale, N.Y., is ready to consider jobs paying half the $120,000 she earned as a publicity manager at Lord & Taylor. That’s mostly because she’s desperate, but it also makes sense when you consider how this country punishes work effort. While the first $60,000 of her income would be lightly taxed, the next $60,000 would be hit with what is in effect a 79% tax rate.

How did a middle-class single mom wind up with a 79% marginal tax rate? At $120,000 she would pay $16,500 a year more in federal and state taxes, wouldn’t qualify for the five-year $12,000-a-year cut in her mortgage payments she’s applying for and would be eligible for $19,000 a year less in need-based college financial aid.
