Bill Holter of Miles Franklin has written an opinion piece worth the time to read and consider.
In my view he does a good job of talking about the real world implications of the battle between inflation and deflation currently underway. Near the end he gives his take on how a reset could happen. The time frame is an unknown. Others see a similar end game, but done in stages over time rather than a sudden one time event. Either way the dollar loses a significant portion of its purchasing power when all the dust settles (probably after a lot of volatility drama in all markets). That is the key point for most people to understand and prepare for ahead of time.
