There's no doubt that Hillary is the candidate of Wall Street. Even more dangerous, though, is that she is the candidate of the military-industrial complex. The idea that she is bad on the corporate issues but good on national security has it wrong. Her so-called foreign policy "experience" has been to support every war demanded by the US deep security state run by the military and the CIA.
Hillary and Bill Clinton's close relations with Wall Street helped to stoke two financial bubbles (1999-2000 and 2005-8) and the Great Recession that followed Lehman's collapse. In the 1990s they pushed financial deregulation for their campaign backers that in turn let loose the worst demons of financial manipulation, toxic assets, financial fraud, and eventually collapse. In the process they won elections and got mighty rich.
Yet Hillary's connections with the military-industrial complex are also alarming. It is often believed that the Republicans are the neocons and the Democrats act as restraints on the warmongering. This is not correct. Both parties are divided between neocon hawks and cautious realists who don't want the US in unending war. Hillary is a staunch neocon whose record of favoring American war adventures explains much of our current security danger.
