You have a good point, but I don't think it really stands up. By the time somebody's 50 or 60, they are looking toward retirement, not trying to start the next huge product.

I look at my dad as an example. He's not an engineer, but he makes a 6 figure salary. Once his last kid is out of the house, he'll be 60. Even looking at him now, at 50, I don't think he has the energy to take the risk and start a company. While there may be a few 50-60 year olds with everything needed to start something else, I think the norm goes in the exact opposite direction.
