Price inflation has been a part of our economic world since the last Depression. The total US Dollars floating around has increased just a tiny bit more than the size of our economy, making them just a bit less more valuable with time.
Inflation is rarely questioned because we are used to it and it’s not large. It’s even considered good policy because it penalizes taking money out of the economy by stuffing big piles of cash into a mattress. But it also covers up a lot of sins and makes it much easier to fudge the numbers.
