Your friend and people drawing conclusion from her anecdote will end up with beliefs typical of the Gettier problem.
or did you mean the NPV when joining at age 18 is... see what I mean?
Edit- People who seperate thinking they can earn more money on the outside. People who seperate for family, mental health, or similar reasons make total sense.
It's not rare for people to double-dip: do your 20 in the military, then go work as a teacher or DOD civilian or something that'll give you a second pension.
If you don't blow all your expendable income on a sports car financed at 30% APR, it's also possible to build up a good nest egg by the time you retire. You can also take advantage of other veterans benefits. A friend of mine got more money from his GI bill benefits (tuition + stipend) than from the actual salary he made during his army years.
Quick edit: the military has a mishmash of different retirement plans depending on when you signed up. I think the most recent one is more defined contribution focused and makes it harder to get money before you're in your 60s
Or knock up a stripper, or lose half your net worth when you divorce your dependa, or all the other bad life decisions that tend to plague people in that line of work.
If you can get through the first 4yr unscathed you're probably on a good path.
So, for anyone just chasing DoD pensions and GI bill benefits, make sure you end up as a lithographer or some shit.
As I understand it, the flipside of this was that not very many people in his (very early) cohort survived, in case someone is thinking of this as "easy government money".

Edit: if you're super ambitious, you take the skills from your military specialization (pilot, nuke engineer, etc) to the civilian world and work another 20 years. you're now 58 which is still younger than the typical 65 for retirement, but now on 2 pensions or 1 gov't pension plus a really nice portfolio.
Then - the corps (corporations) come looking for you.
If you join now there is an age it kicks in I think, rather than immediate.
Plus you still have access to things like the commissary if you live near a base. As well as medical insurance for life.
The numbers you are seeing are really the top of the iceberg; my actual take home as a retired E7 is likely to be about twice what the pay numbers would tell you due to VA disability.
So after a take home of around $72k/year and essentially free medical for my family for life, as well as my children’s college paid for (my degree was paid while on AD so they get my GI Bill), we still need to factor in Space A flights, tax free shopping, cheaper gas, gym access, beach accesses, cheaper groceries, etc. etc.
The most recent numbers I saw were something north of 2 million for anyone E6+ who gets 100% VA disability, which is pretty common.
That said, I rarely recommend the career to people. The costs incurred really aren’t worth it unless you get the equivalent of a lottery ticket.
My dad was career Air Force. The free family medical ended when I was 18. PX privileges ended at 21. No money at all for college.
Some situations change that; one of my children is special needs and may never be independent so would stay in my healthcare for life. The transfer of GI Bill is relatively recent but if your father was even 0% disabled (I don’t think there’s a vet that isn’t) California would have waived your tuition to any state school after you became a resident. There are other situations that result in free college.
