It sounds a lot like prosperity theology too. This was argued against in the book of Job when Satan took the position in his bet with God, to the effect of "Job is only loyal because you shower him with riches and nothing ever goes wrong for him".
It's ironic how popular prosperity theology is with American Evangelicals.
Prosperity preaching is heavily ingrained in US culture
But flaunting wealth and saying your acumen caused it turns out to be effective all over the world because people want it. A lot - most - wealthy people dont even know they have enough money to have a decadent lifestyle and dont know where to start. Most are not consciously avoiding something flashy but are also constrained by their peers from being accepted for doing anything different.
So there is still a lust for people that can attract attention based on their perceived wealth.
