I see it more as a sign of how few mainstream alternatives have been proposed. I've been guilty of generally assuming a communist bent when I see a negatively zealous response to the "free market" ideology. I don't act on the assumption, but from my experience, it tends to be the most common result.
Our political system seems hell-bent on only ever having two solutions to a problem, though.
We seem to be stuck at a local maxima[1]. The current system works great for the 0.001% who have all the money and the power, so it isn't in their interest to change it. But there definitely seems to have been a failure of the imagination amongst the 99.999%. Too distracted by social media and our phones perhaps?
[1] There is a lot to dislike about the current system, but there have been far worse ones (feudalism, communism etc).
