Also, while lattes may be a luxury from your standpoint--personally, I prefer black coffee--expensive purchases, for white collar workers, are not. You have to play those "status games" or your infinitesimal chances of getting promotions will go straight to zero. It's not always lattes. It could be something else: eating lunch with the popular kids, drinking with the bosses, etc. But you have to do it if you want any chance at all of having a career.
Furthermore, you need to take a course in remedial math. To be able to afford a starter house in the U.S. where there are decent jobs, you need to skip about (wait for it) a hundred thousand lattes. That's about 5,000 months (416 years!) of forgone coffee. The life expectancy from age 20 is about 58 years. Wrong; play again.
It's funny how Boomers and cappies love to talk about our need to take "personal responsibility" for surviving in the shit-ass world they've left us, but never consider that they should take responsibility (or be held responsible, because that's Bolshevism!) for having made the world the way it is.
