As far as I can see it, "not having a savings account" is primarily a function of money.

Intelligent people have low savings because rent is higher than their take-home pay. Remember that the average American family lives under $50,000 / year wages. That's a family, which typically includes TWO wage-earners.

Average wages is below $35k / year. Drop out a bunch for taxes and it becomes difficult to build up savings.

Go to "below average" jobs and you straight up are unable to afford rent, unless you band people together somehow.
