Yeah he is kind of a liberal. One of his books and his blog are called 'Conscience of a Liberal' after all. The Krug is not anti-corporate, neither am I. We're anti-corporate abuse. You don't have to be anti-capitalism to be anti-crony capitalism

Corporations serve a vital role in society, but it's not that role that anybody who understands the issues has a problem with. It's when they run amok, which is what we're dealing with. If you're unsure of what they're actually doing, we can discuss that

I don't have any sources on hand because that's not really something you source because the cat has been out of the bag for quite some time and most content is about the details. Plus it doesn't get nearly the attention it should. I mean very few people even talk about arguably the most corrupt money-maker of all time (US military/mercenary).

I would just recommend keeping up to date on Krug's and Robert Reich's blogs. They are unquestionably the most qualified of all the people who are vocal on the subject, and that's why I defer to them.
