That's an easy thing to say, but not useful as a way to move forward. What does that new system look like? How does the transition happen? If going with one of the traditional replacements for Capitalism based in some kind of Marxism, why should anyone believe it will work this time, when it has failed every other time? The typical, "we'll do it right this time," isn't going to cut it. Simply eliminating Capitalism doesn't put a society on the fast track to peace and prosperity, it simply changes how the few end up with power and control.

Until the author actually moves to a Communist country. It's safe to suggest that this "system change" is unrealistic.
