You can afford better food, nicer place to live (living next to major highways/trains results in lower lifespan due to the pollution), can have more autonomy and respect in the workplace (lots of pesky things like hormone levels change when you are perceived by others as 'high-status' vs 'low-status' and status is more often than not determined by money), and MOST importantly, at least in America, you can afford healthcare. And getting treated for a disease/ailment has a very positive correlation with surviving it.
