“Saving” is a catch all term that implies investments. I seriously doubt this guy is letting his money sit in a checking account.

“Have we seriously reached a point where people who are responsible with their money and save for the future are called “childish” because they choose to live a frugal lifestyle that younger people are forced into by necessity or irresponsibility?”

Of course we have. What, are you new to America or something?

Your 35 year old friend with two roomates living in his (owned) house is far smarter than you or the dumbass ex-girlfriend who dumped him.
