Even with no debt, you still have a lot of bills and monthly expenses. Sure, it's great, but I wouldn't just walk away from a job because of no mortgage or car/education loans. There's still monthly bills and saving for retirement and college. Food, clothing, insurance, all extras. And taxes... always taxes. By the time you pay all of that, you're not left with an extremely large amount of money. Or at least, we're not. But, we do try to save a lot every year for retirement and college. If we had a mortgage and loans, we couldn't save half of what we save now.
