You can have 6 figure income and still not be rich, 100.000 to 999.999, and whilst they definitely Arendt neglible amounts of money it’s not making you rich either - many regular jobs has a six figure income.
But I agree, if you even feel the need to mention money at all - you’re doing so to brag, there’s no other point to it, besides that the majority of all the sensationalist writers can’t even put their money where their mouth is, no pun intended.
