If the free market supplies the "just right" amount now and in the future supplies less, deflation can result.
Why does that make deflation a good thing?
Why does that make deflation a good thing?
Because deflation is an increase in the purchasing power of the currency. It isn't any more complex than that. Why do you continue to reject that a dollar growing in value is a bad thing?
I suspect it's because the only deflation you've witnessed in your lifetime is the wrenching kind caused by government price-fixing of the interest rate. A free market wouldn't see that.
