Truly the rich want to get richer, and do in cycles. At the end of these cycles more regulation is put in to detour the very greedy from taking everything. Unfortunately at the end of the regulation cycle, the regulation is removed (Glass Steagall), and the cycle starts over.
We are now at the start of the re-regulation cycle. If we fail to elect a president that will limit “robber baron capitalism”, the Armageddon scenario may play out, but likely we will put limits on the new combo finance and banking houses, and go along in the next tick of the cycle. The new creative financial products that are heralded as the gift of “a free market place” are crap and need to be eliminated.
