More than half of millennials, or those born between 1981 and 1996, think that they will be millionaires at some point in their lives, according to a 2018 survey from TD Ameritrade. The reality could be a lot less pleasant, though, as a report from the Brookings Institution, first covered by The Economist, makes clear.

"Median wealth among millennials in 2016 was lower than among similarly aged cohorts in any year from 1989 to 2007," when the Great Recession hit, the report says. "Median wealth among millennials was about 25% lower in 2016 than among similarly-aged households in 2007."
