Paradise Valley and Central Phoenix have more “old money” which tends to be quiet money. But there is plenty of serious money in North Scottsdale now too....robust golf scene & night scene in N Scottsdale.
There are posers here, sure. But no more than in any large metro.
Paradise Valley, Arcadia/Biltmore, and North Central Phoenix are older money areas. Many older homes in those neighborhoods have been updated. Additionally, people living in those areas aren't often unattached.
Scottsdale has more of a reputation for debt ridden phonies pretending to be rich. This has gotten worse since the 1990s.
In the late 2000s, when the last real estate bubble burst, repo companies were quite busy up in North Scottsdale.
Phoenix/Scottsdale is more full of posers/phonies than a lot of similarly sized metro areas. The list of Fortune 500 companies headquartered in Phoenix is weaker than a lot of the other Top 20 metro areas, which creates less overall affluence and the need to be a person in a lot of debt who imitates being rich. A lot of people with money who live in Phoenix moved there later in life after making their money elsewhere. Working in the medical industry is good in Phoenix because of the large amount of 55+ people living in Phoenix needing medical services.
Dallas and Houston are both famous for 30K millionaires in their requisite BMWs too, lol. I’m a Texan & know that culture well.
Dallas is known for pretention too. There were nights in the early-mid 2010s that I was out in Uptown Dallas before Uptown Dallas went downhill. During that time, the nightlife scene in Uptown Dallas was a lot like nights out in Old Town Scottsdale. Women were extremely uppity and rude. Lots of male competition with good looking women with bad attitudes.
In Phoenix, if a man spends his time only looking for women at Old Town Scottsdale bars and on the swipe apps, it's often going to be a really bad experience that would skew his perspective on Phoenix. Old Town is likely the worst thing that someone can do for in-person approaching. Yet, a lot of men in the area buy into the Old Town hype because there are a number of attractive women who are known to go out in Old Town.
The term 30K millionaire emerged in the 2000s from what I remember. In the 2000s, 30K was a common starting salary for entry level jobs, often right after college. With inflation, the term now needs to be at least 40K millionaire.
