now that's a phrase I have only heard in one other context: as an alleged quote from former Boston Celtics player Isaiah Thomas (who was really about 5'7 despite his official listed 5'9; yes, professional basketball player in NBA). This was around 2017 when he had just come off a career year and was soon due for a contract extension in the low 9 figures. He got injured and bounced around for a few years before eventually leaving the league, and never got that payday.
Sure there might be a dozen individuals making over $300k but most COBOL devs live in the deep south making less than $100k for their entire careers. Fine salary, but that line of work is severely limited and the salaries do not reflect how valuable that work is.
