The equilibrium position is you can invest your own money, then take money off others, invest that too and take a %. The danger zone is for small investors, where it doesn't make sense to advertise to them because the regulations are too demanding, margins too small and people tend to be flighty or need lots of hand-holding. That is basically why it there aren't "invest in stock!" signs on every ad stand. And good financial advice tends to be boring and doesn't change much. The same strategy tends to work in all weather - invest a little bit in everything, invest a bit more in things that do well and try not to take on unnecessary tax burdens.
