If everyone was as stingy with their money as this guy is, the economy would crash. We need spending to drive growth and provide employment. If everyone hoards cash and refuses to spend it, you get the crash of 1929 and the Great Depression.

Time invested in saving money is not always worth it. If you're making the equivalent of $50 an hour, an hour spent agonizing over how to save $25 is a net loss for you. You are not maximizing your utility.

Saving money will never be an end in itself. It is only a means. Who is more admirable: the guy who saves obsesses over spending the minimum amount of money and lives in a cabin Montana, or the guy who goes deep into debt to get a PhD, become a doctor, and save lives? I think we all know the answer to that. I'm not saying that everyone needs to get a PhD or that you shouldn't go off in a cabin if that's what you want, but don't put yourself on a pedestal for your self-indulgence.
