Well my humble opinion is that there are NO business cycles save one, an annual cycle driven by the seasons.
The rest is driven by the ebb and flow of policies of governance, emerging technology, war and various other issues driven by human choice.
The fact that we have gone from wise to stupid in the way of monetary policy may be a recurring phenomenon but it isn’t cyclical. Human choices aren’t inevitably governed by a cycle.
Rather than holding a fatalism that is engendered by the belief in cycles in human behavior, I prefer the optimism that people can get a clue and keep it for thousands of years perhaps.
Teach your children well.
Agreement and would add two words ...
Teach and prepare your children well.
