After the financial collapse of 2008, and the massive federal bailouts of the very people who caused it, and the failure to investigate ANYONE for malfeasance, Americans have no excuse to think that Wall Street's interests coincide with those of regular Americans.

As for the foreign interests you cite, a similar situation obtains there. The interests of the people there only rarely align with those of their ruling elites. 

That's the scary thing: American billionaires and bankers have more in common with Russian billionaires and bankers--or Chinese or German or Japanese--than they do with American citizens. Globalization has made national identity obsolete for the people at the top.
