We're lucky in that being an academic means you're never going to be rich, but you'll also always have enough to live. For us frugal folks, my partner's salary has been plenty, and now that I'm not putting all of the money he earns towards growing my business, I'm actually doing better for our family by making nothing (rather than by creating debt). Yay for small incremental progress.
Seriously, though, my partner and I are really starting to see the benefits to having a state job, where the salary is lower but the benefits are better. The famous study that said the ideal household income was $75,000 has now been raised to $83,000 (and up to $92,000 for pricey California), and we haven't hit any of those thresholds, yet by living simply, we've been pretty happy.
So, more money, more problems? It would seems so, according to the study. More money doesn't make you happier; your happiness levels off (or plummets) as your income increases. So, cheers to freedom and free time and having just enough money to enjoy life.
