That's such a good analysis, wow and actually that thing of the wealthy people not living in the neighborhoods that are considered for the rich, i had never looked into it that way. It's so right, i have noticed it.
Another mistake or disastrous belief most well educated people have is buying alot of shit in their houses, you know someone always wants to buy the coolest refrigerator or car the latest model. Or to go the most expensive hotels in the town to keep their job reputation in the society. The things we watch on t.v when they advertise samsung smart refrigerator and they make you believe that if you don't have it you ain't rich and so we have to have it.
From what you wrote above there, i understood another important thing
Living life as a minimalist.
The less the things you need to buy, the easier it is to invest your money or rather keep your money too.
