The world of finance is free from control, financial flows are not subject to the same taxes as everyone else, and participate in the legalization of financial Mafia whose incomes are an insult to democracy.

In addition to an unstable system, Wall Street makes desolate by repeated and successive of "financial bubble" bursts, whose astronomical losses are disgusting as they could be put to better use.
