As another poster said, the editorial says that this net worth is that of the "typical" household. He doesn't define "typical." If he speaking of the average household, then the number is skewed by the very rich. If he is speaking of the median as he does in other places, then people should know about as many with a net worth over than amount as under that amount.

Not necessarily true.
Your net worth is dictated by the area where you live. For example, in the part of South Florida where I live, the average worth of a four bedroom home is $400,000+...and we're not the "very rich"; as a matter of fact, we are mostly working stiffs.
When you calculate the worth of your home, your savings, your retirement plan, etc., that net worth increases.
