There’s another reason total net worth is not impressive. It’s been established that wealth has concentrated upward. It’s entirely plausible that the top 15% (or so) of households have gotten wealthier, while the bottom tier of the economy (and it’s a very big tier) is close to 0% net worth, with no options to improve their situation.
--and we wouldn't want it any other way. 100% of America gets sick once in a while, but only 0.08% of Americans are doctors who get paid to heal the sick. Everyone listens to music song by a tiny fraction of the population. Most employees like to work 40 hours but there are a few who prefer to work 80 hours (while most of America doesn't work at all).
The fact that so few make so much is the way it should be.
That just ain't so. There is nowhere on Planet Earth where opportunity to better oneself is greater than in the U. S. A. It's been proved time and again. It's always amazed me how successful people who work hard, discipline themselves, and act morally, are said to be "lucky." Luck had nothing to do with it.
