Goldman positions itself in the middle of a speculative bubble, selling investments they know are crap. Then they hoover up vast sums from the middle and lower floors of society with the aid of a crippled and corrupt state that allows it to rewrite the rules in exchange for the relative pennies the bank throws at political patronage. Finally, when it all goes bust, leaving millions of ordinary citizens broke and starving, they begin the entire process over again, riding in to rescue us all by lending us back our own money at interest, selling themselves as men above greed, just a bunch of really smart guys keeping the wheels greased.
