Depends a lot on department and situation. Course 18 (math) doesn't pay that great while course 6 does. If you have a chair you can pay yourself more; if you take a non-academic role (dean, provost, department head etc) you can get more. Even when you have tenure you get reviews and raises just like any other job.
Point of reference: my gf's ex is a tenured prof in a non-engineering field. B/c child support etc I know what he earns. Adjusted for inflation, my summer consulting gigs (before the 1980s AI winter) earned me over 50% of what he makes all annually including his own summer consulting. I'm sure if he were in computer science he'd make more in a month than I would have made all year.

This is the one thing that has always struck me as odd abut the FIRE community. FIRE is a good goal but it's highly abnormal for people to retire early with these very low annual salaries for themselves. Sure, it works if you're a single childless 30 year old. But you also generally have to be comfortable staying single and childless if you're going to "retire" to $25k/year.
Also, even if people budget a $25K/year retirement there is always the possibility of needing long term nursing home care in the last years of life. (Say, if you're a football player that suffers dementia later in life.) Depending on the quality of care, that can wipe out even a $1M nest egg. It's a big financial concern at that age. It's not covered by insurance the way that, say, a heart attack or stroke is.
Doesn't the average NFL player have a life expectancy of 53-59, and you can only collect the pension after 55? They can move it foward starting at age 35.
Cynical me says it's a political nothing burger.
I would sort of expect that the NFL Players Association had something to do with establishing it.
$1M is not even close to that, especially not for a young guy who has to pay for the next 60 years of his and his family's existence.
Don't get me wrong, it's a good starting point, and you can definitely be reasonably secure on it if you invest wisely and continue to work (e.g., buying a reasonably-priced house in a stable neighborhood and staying in it long term; this will take about 1/3 of that $1M, btw), but it's not enough to be truly independent. A single serious lawsuit will easily drain $1M, for example.
I imagine this guy can, given his uncomplicated expectations of life.
We live in an interconnected world and there isn't enough money in the world to make your actions consequence proof.
An independent person does not need the goodwill or approval of any other person or small group for their well-being or prosperity. If you are ever going to need a paycheck again, this is by definition not you.
Independence ("fuck you money") is about being able to be honest with anyone, even if it means giving a measured, well-deserved "fuck you", without having to worry that your ability to feed and clothe your kids will be jeopardized. It's not about being above the law or anything like that.
Also, how much professors make varies quite a bit. An engineering professor might make $100k from the university. If they are particularly motivated, you have professors who write books, play key roles at companies, consult, or give expert testimony. They can make quite a bit off those secondary activities but it isn't automatic.
What exactly is "a lot of money" (and how much do you think MIT professors are paid)?
I think point #6 is more relevant than point #5.
