Deflation is a problem, but not for the reason mentioned there. The reason deflation is an issue is because it makes holding cash into an investment strategy. If the price of goods is dropping, the value of money is rising, so the more cash I hold the richer I get. This obviously dissuades people with cash from investing their cash into actual productive work, which means fewer jobs. There was a small deflationary bump in American history around the 1930s that helps to illustrate what can happen in a deflationary spiral.
Like interest on a bank account? Holding cash is already an investment strategy. Bonds are a thing. People have options to hold cash and not lose purchasing power. One of the traditional ways people tackle inflation is they demand interest from the banks sufficient to cover it plus a little more to account for time value of money.
It is rather unlikely that giving people an option that they already have is going to cause a problem. One major benefit of money is that people can hoard it and there is no cost in the real economy because all the resources are still there and prices can just adjust to the amount of cash in circulation.
> here was a small deflationary bump in American history around the 1930s that helps to illustrate what can happen in a deflationary spiral.
The US came out of the 1930s with an economy that was capable of overcoming almost literally the entire world. Again, the evidence that deflation was some sort of major problem is questionable, it seems to have been associated with the creation of one of the most dynamic economies in the history of history.
And the idea that we have this one clear lesson from one instance back in the 30s is just weird and unbelievable. That isn't how history or complex systems work.
