There is nothing wrong with securitization. it has been the basis for capitalism for hundreds of years. You can argue about the flaws of capitalism but it is still the best system devised, so far, in human evolution. But theft is not capitalism.
Unfortunately the United States Supreme Court seems to be moving dangerously close the edge by allowing theft to prevail and the Securities and Exchange Commission is arguing with the court about it. For those concerned about the future of the country now i the time to start making calls to public figures and letting them know how you feel about this.
