With fractional ownership, it is not a lifetime commitment. Also, purchasers are not making their decisions under high-pressure deadlines. It doesn’t have anything to do with rich people.

It's taking advantage of uneducated and unsophisticated people, in the scope of timeshares.

Sad truth.

Well stocks are fractional ownership too. They don't have upkeep costs and someone doesnt get a better seat in the plane. But some stocks and plane fractional ownership could also be a scam when the debt exceeds the gains to be made by investment. The zillionaires may be sharing the plane and upkeep costs but what if one guy gets the priority to use it before anybody else or that shares were sold to other buyers at higher prices.

To a degree. But look at the S&P over time; it is profitable. Look at timeshares, where perhaps 95% of purchasers regret their purchase.
