Meaningless statistic.
My household net worth was approximately zero as I crossed over into my 30's, even though my wife and I were both college grads and working "professional" jobs. If Debt = Assets, your net worth is zero; you are BROKE. Now I'm in my 60's and money is no longer an issue.
Was I "poor" in 1979? Should I have gotten some sort of debt relief? Welfare? Subsidized housing?
Or was that about where I could expect to be, given that I grew up poor and had no parental support after age 18?
If someone fails to graduate from high school, doesn't diligently pursue gainful employment, has babies out of wedlock, and spends what little s/he has on frivolous crappp, then they deserve to be poor. There is no inherent injustice in "inequality," no matter now many politicians try to pretend that there is.
