I think you're both right. Capitalism is an important part of a liberal society. But when we let private institutions become all-powerful then they can erode our freedom too. The problem isn't government or enterprise, it's the idea that only one of these things should be paramount. We need government to do unprofitable but necessary things and we need enterprise to pursue risky things. And we need government to regulate enterprise and enterprise to hold government accountable.

You can name a lot of symptoms of the problem but at its heart there's a lack of accountability in any of our power structures whether they be corporate or government.
