I wonder to what degree generational culture plays a part. My father, for example (born pre-WWII), would never buy growth stocks. Not even when he was young. He bought only dividend yielding stocks, reinvested 100% of the dividends and never sold anything until his retirement. My generation (X) has a more balanced approach, with a mix of growth and value stocks dependent on risk tolerance, trending toward value stocks the older we get. Moreover, a lot of us learned some hard lessons from the first internet bubble.
Granted that they're still younger and should be in a more risk-tolerant phase of life, but what I see in Millennials, and Gen Z especially, is a culture of growth-only, with no interest in boring old investments that are intended to earn and build value over long timescales. I think at least some of this has to do with the gamification of investing; in my Dad's time, a normal person couldn't just sit at a brokerage and watch a stock ticker all day. Free trading has intensified it by removing the barriers to full-time gambling. Remember that Millennials are a much larger generation and we're just still early in the period when they're growing wealth; I wonder if what we're seeing isn't the beginning of what it will take to change the culture... or if we'll continue to see endless bubbles because the steady-as-she-goes, long term investment mentality is just disappearing in the face of permanent FOMO. Sure, it's not glamorous, it won't make you a millionaire overnight, but that's really not what investing your savings should be about.
