Besides, you could also live as if you make a million and still have 74 million a year after tax to save.

But, why?

If you're making $150 million / year, why would you "live as if you make a million"?

Like, what are you saving up for? A rainy day?

To become a billionaire, of course!

I mean, yeah, I wouldn't care, life's too short not to use the money for something.
