  Sure you do. It's called a revolution. The USA even had one, once. So did the Soviets, and the Chinese, and the French. You need to brush up on your history.  Again, I ask: what would you replace American Capitalism with?  Each of these was a process. The Americans didn't just up and one day fight off the British. There was a very long series of grievances and progressive thinking towards a new system that started before they even colonized the Americas, and which escalated after. While in these cases, the "tipping point" happened relatively quickly, the framework of change had already been generated among the people, who were ready for it. You can't just switch governments one day without any preparation.  Regardless, the era of Revolutions is over, at least in the First World nations.  I am an unapologetic critic of capitalism and I will be the first to say no revolution will occur in the USA.
