In the US, that would be anyone with a net worth of $1.9 million or more, counting equity in one's home (https://dqydj.com/net-worth-percentile-calculator/).

That's not even considered wealthy anymore. According to a Schwab survey, you'd need $2.2 million to be considered wealthy in the US (https://www.usatoday.com/story/money/2023/10/23/what-does-it-take-to-be-wealthy-in-america/71237797007/).

I promise you, what people with a few million dollars net worth do is, at worst, more conspiuous consumption than those with lesser means. That's certainly bad for sustainability, but not worth being scared about.
