Interesting questions and perhaps you should maybe read the post again. The point is that people will not allow change especially if the current system works for them. If it all is working so nicely, why did we have multiple financial melt downs in a couple of decades. Why is our income distribution the most skewed in more than a century? Why is global growth so low and far below population growth? The point is very simple. Those in power will not be motivated to accept or allow change as the status quo is working for them.
