If you're alluding to the golden ratio (which is closer to 0.618), I don't think the average normie has even heard of it.

0.1 is a more realistic goal for many, it also depends on where one lives etc. I'm in some FIRE-themed subreddits for example, where folks are generally well-off, with 6 figure jobs and brag about their net worth and celebrate hitting the milestone of $1m USD, but at the same time complain it's not even much of an achievement these days and you need at least $3m to retire. I don't think they own any BTC, because it's hardly ever mentioned, while they mention stocks, bonds and cash. So there are cohorts like that too.
