IMO. financial markets are not free, and the big players want it that way. This helps to explain why stocks have been screaming higher (in the longest sustained increase in history,) while volumes have fallen. As fewer people are in these markers, big houses have seemingly done well, because of the increasing power they have. This is an incestuous tower built of cards.
Look at "bail in" as an example of how our system has been corrupted along socialist lines.
