I've been saving money essentially since I was born. At this point in my life I currently don't have a ton of expenses. I share an apartment with my GF, car is paid for, zero debt, no student loans, and I have everything I need in life. No kids, in my late 20's.
It's scary to think how thin of a safety net people have. I suppose some people just rely on credit alone for emergencies. I'm sure the thought of retirement isn't even on many people's radar.
We need to teach basic finance in public schools, probably starting at the junior high school level.
