You don't have to have that high of a net worth if your spending is lower. You only need to save 25x your annual spending to retire. If you only spend $30,000/year, you only need $750,000 to retire.
"only"; it's a very privileged position to be in if you are able to earn so much and spend so little to be able to head in that direction.
Personally, after spending most of the past decade in substandard / 'affordable' student housing, I'm now very comfortable with owning a house and making ends meet at the end of the month. I've got enough savings to keep afloat for a year if I somehow lose my job, and I even have some in the stock market because savings account interest is trash at the moment (iirc because of European money lending policy, causing cheap mortgages, causing low savings account interests, and causing climbing house prices from both low mortgage interest rates + investments in real estate).
