Personally, I myself am NOT rich... just a little better than most

anyway.. being in business and doing a lot of sales, I find rich
clients tend to be scroogy most times, while some are real
spenders.
Then there's another kind, the kind who looks like they hardly buy
new clothes, never own a car and commutes by public, not flashy
very humble .. until they tell you their budget during a
sales!
fwah... makes my month's profits man...
Rich parents are so many, but most are way too busy making money,
hence their kids grow up thinking money grows from inside parents
pockets.
However, I have commonly observed that truly rich people, are much
more thriftier than the average or high income earners.
As for flaunting - this in itself is an entire topic on its
own...
