Maybe companies try to gamify growing inside the company, make it look like an achievement. I've worked at a company where most engineers have been in the team for 2/3+ years, maybe more, some of them first and only job, so far. Most of them were probably low-ish to medium salaries but they were happy with the team and the company. Had no plans to leave or try to argue for salary raises. confortable Some people simply don't care so much about money and will be happy to have a nice stable environment they're comfortable with.
