It's an outlier, even in America. I live in the US and no 23 year olds at my company are making 100k/year, lol.

Most jrs in America are working jobs like this - https://www.indeed.com/viewjob?jk=0dcd3d05ab694ba8

Not really the case in any of the high cost of living cities - when I graduated undergrad in the mid 2010s, my peers where getting offers from Microsoft for 100-120K for their standard out of school dev positions, Amazon was better as was Apple from what I recall. Plenty of 23 year olds making that much?
