Lotta hate in here, but try not to focus on that. Remember that HN is an unrepresentative group of the entire audience that article addresses. I'd guess most HN readers are probably doing a-ok salary-wise in the frugality world (but if you _must_ live in {SF,NYC} forever, then probably not).
Spending-wise? No idea. But I'd recommend trying not to be too put off on the "work hard" advice, you probably already work hard and will get more out of the "spend carefully" side of the savings equation.
Life isn't a code review. Even if you think something is 99% wrong, it might still be 1% right. And if that 1% can get you retired a decade earlier, I'd give it some serious thought and just ignore what you think is wrong.
