Not necessarily. The inflation calculator is essentially a money converter, not a price converter. The inflation calculator is found in several places. The only one I've used was from one of the Federal Reserve Banks. I hope they are all the same.
But, the prices of different things do not all change at the same rate. And the changes in typical earnings for a given sort of employment also do not necessarily change at the same rate. And the products themselves change, too, usually. Still interesting to think about the old prices.
On the subject of changes in prices, however, I think that ammunition used to be relatively more expensive than it is now, compared with the price of firearms. Also, over the last, say, 20 years, there have been wide short-term flucuations in the prices of certain kinds of firearms like pistols with high-capacity magazines and anything remotely resembling an assault rifle, all because of market forces. But prices of more ordinary firearms like Marlin lever actions have been relatively stable, though the prices have steadily risen. Other models and brands have simply gone out of production because costs overtook what the selling prices were or because of what might be called the product life cycle finally came to an end, like the Winchester Model 94. True, someone else is making a copy already, but most people that wanted one had one. Winchester had been making every possible variation and commemoration to sell them.
