Think a fixed car payment, fixed rate school loans, fixed rate mortgage, gas.
You can even put a silver lining on those that if you're paying back fixed rate costs established in 2020 with dollars from 2023 that have less buying power, you're getting a discount.
Continuing inflation has more to do with overall costs being higher and labor is a big factor. My local MCDonalds is raising prices now to make up for the huge wage increases they needed to find workers.
Profits are up too. I would even suggest that profits are up a much larger percentage than wages. Along with wage increases having a much smaller increase impact on prices compared to the wage increase for most things. Meaning a 10% wage increase isn't going to create a 10% price increase, but something much smaller.
COVID dollars are gone, but the supply chain impacts are still real. Not nearly as dramatic as initially. But, much slower to recover to "normal" or the prior steady state than the time the disruption took to take place. It's relatively easy to stop everything and break all the supply chains. It's significantly harder and takes more time to build it back up. After all, the old steady state was the result of the beginning of time until then to create it. It'll be much faster the second time.
Now, if you had bought a WDW season pass in 2020 with 2020 dollars at the 2020 price, but that pass wasn't for use in 2020 but for the year 2023 instead, and as a bonus you actually paid for it in 2023 using 2023 dollars, that would be a huge deal. Both the lower price, and the dollars with less buying power getting the same value. You would have doubly saved on the deal. Of course, they didn't actually sell that as a product. Likewise, if you had bought a one year Magic Kingdom passport in 1983 but only paid for it now in 2023 with 2023 dollars, it would have been practically free. Also not a sales option they offered, unfortunately,
