This is a good point, in fact recently there have been a spate of articles claiming that millennials are saving too much (in cash at least) and not putting enough in the stock market:

"42% of Millennials are investing conservatively, compared with 38% of Generation X investors and 23% of baby boomers, according to the Fidelity survey." source: https://www.forbes.com/sites/andreacoombes/2018/03/13/millen...

But having lived through 2007-2009, it's no surprise they have a preference for cash in the bank.
