Personally I don't believe that the control freaks and property thieves can be kept out for an indefinite period of time. I doubt that Moses would have written the eighth commandment (thou shall not steal) if there were no thieves in his time. I don't believe that Men are innately either good or evil but that we learn to be so. The U S Constitution basically held together for 100 years. How long will John Galt's gulch last?
