I think you illustrate here why people tend to to not be as careful with their money as maybe their pocketbook suggests they should. When they think of the prospects, they take it to the extremes.
No one on here has suggested the things you say here or to live like a hermit. It is clear, you didn't read anything on the Mr Money Mustache site because if you did, you'd see that while he is very, very frugal, he also travels, eats out, has one of nicest homes in his neighborhood. Oh...and was able to retire in his 30's due to his disciplined lifestyle so I'm pretty sure he is having a more enjoyable life at his age than your or I are working for the man 40 hrs + a week.
It may not be for everyone, but try and at least paint an accurate picture. If is is so terrible, you shouldn't have to continually exaggerate to try and make your point(s).
I will admit I know nothing about the guy but everyone's circumstances are different. If he is what you describe I would bet he had $0 student loan debt and mommy and daddy probably helped him with a lot.
