Coworker at Fortune 500 does this. Old housemate at different Fortune 500 did basically this (slept on the floor, only owned cardboard boxes, one week of clothes and a car).
Both of these people are incredibly rich. One came from parents with oil and financial sector money. The other has multiple real estate properties. Both have six figure incomes.
Other people I know in the tech sector are less extreme, but nonetheless have various plans for exiting the corporate world so that they can feel financially independent enough to retire early and then work on problems they find enriching/bring value to people rather than shareholders/etc.
Though one of them was obsessed with immortality and saving up for when cryogenics and Kurzweil's singularity were figured out. So I guess it's not all about the rat race for everybody.
