I'm the same age than OP, but spent most of my adult life living paycheck to paycheck. I have only obtained a comfortable income and bumped up the class ladder during the last couple of years, when I finally moved to the US working for Big Tech. I don't know what is the point of this article other than a humblebrag. What should the takeaway for people struggling to make ends meet while working bad, low paid jobs be? Should I feel bad that I'll never get to retire before 40 because I didn't ride the high income wave since my 20s?
