The real world works on the principle of 'Prey and Predator'. Number and health of predators depends on number of prey available. The time evolution of two species goes in a predictable manner.
If we are able to lure many millions of small investors to put their savings in to stock market by sustained advertising etc, the 'prey' population will be fairly constant, and 'predators' can happily continue to make money.
In fables that we learn as children, a kind hearted man teaches parrots to repeat 'be careful of the hunter'.
Parrots nodoubt learn their lessons well, and when caught irretrievably in the trap, do not forget to chant 'be careful of the hunter'.
If we want to help the situation, and aim for general prosperity, there is enough experience available from advanced economies and overall functioning and behaviour of free market, to rethink about strategies for larger good.
Clever strategies like hedging funds are needed because direct investment is vulnerable to violent ups and downs etc. caused by various things.
Primary markets alone are not generating the wealth, and many more evolved options proliferate. Operators with 'deep' study, (meaning thereby those who have learnt their lessons through numerous 'small gains' and 'large losses') are more comfortable with complexities.
New entrants have no clue whatsoever about overall happenings and readily confess to it, while hoping to make big any how__ by 'speculation' or 'investing' etc.
