Communism is totalitarian rule by a central government headed by a small oligarchy and led by a single tyrant. If you want to take things to a "logical conclusion", how about this one: In the US, the status quo is headed towards -- if it hasn't already happened -- rule by an oligarchy of utra-rich with an almost complete control of the political process, financial system, capital, judicial process and so forth. Everybody else will be at the whim of this small group, basically one class of working poor. In other words, a system that looks more like communism than capitalism. Use modern day China as an example of what this looks like.
You and I choose democracy over monarchy, dictatorship and rule by a small oligarchy don't we? If so, then communism is out of the question. So too is rule by oligarchy. The only question remaining is what do we do about it. The genesis of the tea party before it was corrupted with Koch money and other extreme right wing groups also recognize the path we are on and are also putting forth their ideas. So great, assuming you don't support the status quo, let the best ideas win in the democratic process.
Regarding what I'm guessing you thought was a brilliant point about Greece and Venezuela, my reply is "so what?". What I keep hearing from the conservative echo chamber is that there is no better system than the status quo. I'm just pointing out that there are other systems that are working quite well. Why would you say that Denmark is headed towards a Greece-like fall? Compared to the US, which has a gross government debt-to-GDP 106%, Denmark's GDP-to-Debt ratio is 50%. The trends for both countries is towards lower debt, but I'd prefer 50% to 100%, wouldn't you? Just saying that its time to get your head out of the echo chamber-bucket and start looking for alternatives rather than listening to old men yelling lies at the public via radio or FOX which are paid for by the oligarchy .
