Retirement is going to be pretty boring for a high performer, so you either have to convert that cash into starting your own business or likely keep working the same job you already have. Entrepreneurship might have a certain appeal, so I wouldn't discount that to those who have that dream, but if you stay in a job then you have to start asking what all that money is going to actually buy you. Both incomes are going to get you to a point where you already won't be able to spend it all.

Realistically, the question isn't meaningfully answered in isolation. One would have to see the bigger picture to put it into context.
