Did George Washington have experience as a career politician? No, he was a general in the army and did a lot of physical work in liberating this country. None of our candidates have had to fight a war just before being put in office in order to even have a country to run.
It is really quite simple, though it takes common sense, to run this country (and you have to be on call 24/7 for threats from any source, whether it be another country or another Katrina). All one has to do is uphold the original constitution with one simple amendment: No person or group shall initiate the use of force, threat of force, coercion, or fraud against another person or their property. Any rules that clash with the original constitution would be ruled invalid and stricken effective immediately. No money would go to the FDA or other regulatory agencies: the private sector would assume their jobs and probably do a better job because of competition.
What would be left is a government that protects its people from initiatory force, threats, or fraud. We would still have an army (as long as this doesn't become worldwide, other nations are still likely to attack). We would still have police, prisons, and courts for those who insist on breaking the law. But we would have market freedom. People would be able to market vitamins--the ones that market crap and fraudulently claim that they do stuff they don't would get a poor reputation and go belly up. We would see Big Oil go bust as new energy sources pop up. The big drug companies would have to start putting money and research into cures or risk going bust to some upstart. Monsanto would go belly up if they continue pushing genetically modified foods, as soon as someone perfects the process and actually succeeds in improving the food supply without destroying the environment or our health in the process. Wal-Mart would stop getting harassed for being better than others at what they do, but would be held accountable for initiatory force or fraud, if they do in fact do it.
And, the Watchtower Society would be laughed out of business. They do initiate fraud to get people to join, along with death threats. They coerce the courts, and even initiate force when doing so is helpful to their bottom lines. Each time they do anything like that, they would be prosecuted. And that includes much to most of the pedophile defense that they commit, threatening children with death if they blow the whistle. That alone would probably put them out of business and in jail for a good long time, while those trapped in the tower would suddenly be set free to pursue their education.
