Pure Democracy is just mob justice where the minority have zero personal rights. I prefer a Constitutional Republic with a limited democratic element as we have in the US to choose our representatives. We need to enforce the laws we already have, not rebuild the whole system.
And who writes the constitution?
I mean if you build a new government, who gets to decide what's in the constitution?
The Constitution was written by guys who were supposed to be updating the
Articles of Confederation. These guys simply wrote the Constitution, on their own, without authorization by the people. Then, they used their authority to present the Constitution rather than their updates to the
Articles of Confederation. The people barely caught on to what they were doing, and it is almost a miracle (good miracle? bad miracle?) that the constitution caught on.
Write your own Constitution. The Constitution allows anybody to write their own Constitution. It's upheld in the 1st Amendment... freedom of speech.
There are lots of new governments right in America. Don't tell me that every corporation doesn't have a government. All corporations operate by their own internal government. If a corporate government was good enough, and received enough publicity, and the people of the USA thought that their corporate Constitution was better, we just might get a complete change of government.
