It's a rich peoples game. Those with mere pittance to invest will not end up with much even if they live a very long natural life and do not touch a penny of whatever they could invest until their death bed. Even then they've have to wait until the very end for that pittance. The whole thing is based on having a enough wealth such that small percentage returns equate to a lot in absolute value. A small or even larger than average percentage return from relatively little wealth is still very little.

To change any of this would be to change the underlying issues of unequal distribution of wealth. The stock markets are derivative. If more had wealth then obviously they'd be investing more. It's not the other way around.

Some believe they can cheat code their way to the other side by gambling which is not investing. Seems to have become popular again in recent times after certain cultural phenomenons. That again does not change underlying issues. A few lottery winners and many more silent losers only serves to amplify inequality.
