The basket of goods has also changed due to technology and living standards.

In 2021 I can buy a bunch of bananas for $1 in the winter in the PNW. This is pretty much not possible for a 1900 factory worker let alone some remote 1800 pioneer. And let’s not even get to differences in the quality of housing like with electricity, or running water, or even a stove with temperature control. (Fun fact; recipes with exact cook times and temperatures only start showing up around the 1930s because previously it wan’t easy to control.)
