I agree you do need to do your own research about what is right for you. However I still think that my advice is right for most people - it gives a comfortable retirement without sacrificing too much of the now. If you are starting to save at 50 it doesn't work of course, starting young is continuous savings is key.

statistically yes, but there are outliers who won't.

Sure, but few people are that high. Even of those who are, 22k (adjusting upward every year) from 25-65 is a lot of money. You can save a little more if you want to retire early, but you are only young once and your time is better spent enjoying youth while you have it.
