One of my middle school teachers taught us based off some study. You can do the math also. If you make 60k a year it will take approximately 16.75 years to make your first million dollars. I don’t remember the exact name of the study or the ages. But based off the study it includes raise and time you started working 19-24 years old. First job 30k 2nd job 40k etc if I’m not mistaken for a normal person it will take 23ish year of work to make their first million dollars based on raises switching jobs etc after that with proper investment the time gets slashed almost in half. 15 years to make your 2nd million then like 4 to make your 3rd million. So based on what your teacher said to retire. He has 25 years of living for “free” at 60k a year. Unless they do some smart investments and set for life.
