You'd be right if we aged like Benjamin Button.

But you're glossing over the downsides of trading your youth away for a hopeful payoff at a later date. Not all of us like that bargain.

I make a fraction of what people in this thread are saying they make. But what price do you put on being 30 and single on a beach in Mexico, happy, with a low stress job? You could look at it as if I paid half my salary to buy back my time.

We all value things differently, but notice that it's your youngest self that's most eager to bargain your youth away.
