Millennials control just 4.2 percent of US wealth and Zuckerberg owns 1% of that, also if you own 0.28% of a Bitcoin you're in the 1% club.

Millennials Control Just 4.2 Percent of US Wealth, 4 Times Poorer Than Baby Boomers Were At Age 34. The millennial generation, people born between 1981 and 1996, make up the largest share of the U.S. workforce, but control just 4.6 percent of the country's total wealth. The 50 Richest Americans Are Worth as Much as the Poorest 165 Million. Not “a lot” of Americans have BTC holdings, study shows, but if you own 0.28% of Bitcoin, only 1% of the world will ever be able to own more than you. Hence putting you in the top 1%.
