I dont think thats right, if you make 10k, per year, saving 9.99k per year isn't going to help. And if you are making 100M if you save 1M per year you could retire. But it also matter on how you live your life, and how comfortably you want to retire. You simply cant make any generalizations like that, or what CNBC did.
If you're a trader, why would you want to retire? You're already doing what most people would like to retire to.
