Only if you cede too much power to corporations.

This is almost exactly the problem, except I think liberals tend to conceive power as independent from 'capital', which is its primary shortfall.

We've already allowed capital to accumulate into too few hands, and now in order to rein them back in a government has to be sufficiently determined as to allow our national economic structures to be damaged in order to rectify it. A handful of companies are responsible the majority of our economic activity, threatening them too severely risks sending our financial instruments into a downward spiral.

There's reason to be pessimistic about the state of things, but I agree it's not hopeless.
