If you make 200k a year, you're not even in the top tax bracket of the US. On 200k alone you can hardly even afford a SFH in SV, NOVA, and NYC.
Meanwhile Elon Musk's net worth can swing 200+ million in a single day. He could buy up an entire neighborhood in those same zip codes you'd hardly be able to break into.
An engineer making 200k a year has more in common with someone making 2k a year, than they do with the Elon Musk's of the world.
This delusion is rampant in professional spheres like medicine and tech.
