The Global Disorder Cycle

Main question: Is the world really oscillating between eras of recession and expansion, or is this logic purely linear and the result of chance?
Argument: The various periods of recession across history are not the result of some events, but the reflection of a cycling logic throughout times.
Conclusion: This logic will never stop : it may evolve, but the mechanism stay the same, pursuing the logic that spanned since the beginning of mankind.
