Im sure this is different for everyone but id like to hear people's thoughts on the threshold of wealth they'd want to reach before they splurge on themselves.
That's not quite how it works.
It is not necessarily an amount. The test is to see if your money generation process works well. If the beta test works and you know you can replicate the results= "You might splurge at first..."
However your mentality then changes completely, and you want to secretly be seen as bring "normal" or even "poor" - so you do not stand out from the crowd/and are not targetted for your wealth/intelligence/ideas.
In my experience the middle class fakers flash their wealth and buy designer labels or ferrari's to "flaunt it".
The genuine elite are literally "discreet". If they do wear expensive/tailored clothes - their labels *(which you have probably never heard of) do not show - and their clothes/cars are not necessarily the loudest. They develop their minds= skills, education, cultural knowledge, travel, etc - and can actually look quite normal on the outside in terms of appearance.
