Always hard to interpret these bottom procentile numbers because a certain procentile has 0 wealth or negative wealth. A quick search says 25% of Americans have 0 or negative wealth. I myself have negative wealth because I recently graduated and I have student loans. A homeless guy with 0 debt and 1 dollar in his pocket therefore can be said to be wealthier than 25% of Americans, and myself. However my quality of life is very good with an above average wage. And I can be expected to start going into positive net wealth later in life as I start paying off those student loans.
I would love to see numbers in lifetime wealth generation or something similar that would take into account that a lot of people are understably at 0 or negative wealth at early points of their life. Otherwise I have a hard time interpreting these bottom procentile numbers. Makes for great headlines though!
