It’s always been there but the showing off of supposed wealth (lots of it rented or fake) makes people think it’s acceptable to do that. It’s not and I think it’s pretty clueless of the people that do it sadly.

I think some people do it because they want more money. I think these people fall under the category of "fake it till you make it".

I agree with you that modesty make people just wants to not talk about how rich they are. This is also another angle, and also self control is also something you've mentioned too. The truth is that a money can make people lose self control and to have money and still keep it together is great discipline.

I wouldn’t even do children in that for a long time, because that gets sketchy too. Other people shouldn’t need to know anything about it.

Yeah, sometimes children are not as mentally matured to understand money discipline. They can become abusive, and proud and even become mean to people who they deem to be poorer, so I wouldn't even tell children too.
