What Venezuela displays is when one-party takes control of the whole system without any opposition to moderate it. Liberals hate the Republican Party, but if your a Liberal, they serve a purpose. Same for Conservatives, although I doubt Conservatives could ever take over all three branches with a super majority. If they did, some of the things that would happen would probably make you shake your head, think Prohibition.
Liberals had full control for two years. And they passed bills even they don't think are good. And made statements such as we have to pass it before we can read it comments. If that statement was done by a conservative for some religious bill, they would have exploded. Now imagine Venezuela doing this for 20 years and this is what you get.
A couple of other things to think about that I've read in this thread. Most European countries, like the US, have a conservative party that moderates its liberal party and vice-versa. Think Germany, no one thinks of their head of state as being liberal. United States has a more socialistic economy now than some western European Countries.
Some countries that are above us on the capitalistic scale: New Zealand, Switzerland, Australia, Singapore, Canada (yes our neighbor to the north), Chile, and Ireland to name a few.
The issue that Liberals are having is that the US cannot be Socialist Utopia and the World's Military Police. There just isn't enough money. So when they see someone like Clinton who wants to keep the latter strong. They know she doesn't or can not move the US to a more Socialist Utopia. Something has to give, eventually our debt will over burden the US.
