Anyone who doesn't believe this needs to watch Client 9 [1] about Eliot Spitzer.
It's very convincing that someone powerful targetted him for his anti-wallstreet policies and sought to catch him with a high paid prostitute. The weird part starts happening when they interview the madam and brothel hustlers who she hired, and find out tons of famous politicians and Wall st execs uses them... but noone else got brought down despite all the private investigations, wiretaps, and FBI investigations, except the one guy pissing off people in power.
Now in 2014 we're back down to nearly zero reputable prominent people in office calling out Wall st or political corruption. Except maybe the crazy fringe types like Rand Paul.
