You do not understand compounding growth.

You could have looked up the numbers for indices yourself, but here you go -

S&P500 -> ~4 million

NDXT (top 100 tech) -> ~14 million.

> just save 100k out of your 170k comp

Yes, that was my starting salary, and that's almost exactly what I saved.

This calculation assumes your salary is somewhat constant and maxed out as the person I was responding to claimed, but in my experience you can expect your tech salary to double every ~5-6 years.
