If I'm to take what he's saying at face value, he's against globalization and free trade because it hurts American workers even if it helps lift people out of poverty around the world. I might deplore the working conditions at Foxconn, but millions of Chinese who would have lived lives of rural poverty have better lives.
Bernie doesn't seem to understand that large corporations need access to financing quite regularly. When GE still had a finance arm, it would use it to finance daily operations. He's taking an unnecessarily moralistic stance on the Ex-Im Bank.
I can't call it moralistic when it would have a net detrimental effect.
