I think the ALICE index is great for tracking pure essentials and survivability, which is definitely important, but it's also not unreasonable to track things that aren't 100% essential.

My household does care if basic games and toys are cheaper or more expensive; we have kids and want to get some amount of stuff for them. If the price changes we will get more or less of those things since our budget for them is limited. I probably won't fall into abject poverty if some non essential things go up in price, but I also will be buying less which has both personal and broader economic impacts.

Absolutely. You need both. The point I’m trying to make is that we only have CPI which drives most policy decisions. However when you need about $40k to just survive and 1/3 of the households make less than $50k before taxes, you also need something like this to make effective policy decisions. Social security payments are a great example. If you adjust them only based on CPI, and essentials get more expensive at a higher rate than non essentials, you create a system where over a period of time, social security payments would barely cover the essentials.
