Or its just a matter of not letting bad players to ruin all the game. Too many greedy blood suckers will drain and kill the cow eventually. The word here is balance to have a sustained long running system that can benefit the maximum number of people.

Note: the blood suckers is not the whole of the capital market of course, they produce value. The problem is some players and some practices..
