Earnings max out at 40-ish
That's what I learnt today:
Whatever you earn at age 40 is likely to be the top of your earning potential. This is one of a gazillion things I've learned from talking with Al Lee, the director of quantitative analysis at PayScale.
Al’s data, which is based on the careers of college graduates, is basically that the salary curve for most people in their 20s is very steep. Then it starts to flatten in the 30s, and then you get into the land of the 3% raise. In real dollars, those 3% raises are not actually raises, they are just keeping up with inflation.
