That's pretty slow. The Treasury and Federal Reserve clipped the dollar down to 4% of its value in only 100 years. At that rate the dollar would be worth 0.02% of its 1913 value after 270 years. And that's under the government's optimistic official inflation rate.
The dollar is about the right value now.
Remember back in the 60s and 70s when to keep things 19 cents or 39 cents, they had to keep making things smaller?
With money today worth 1/10 as much, it is easier to change the price of that “19 cent” item from $1.99 to $2.09 and keep a standard size.
