Two points on the market basket mechanism for measuring inflation: One is that I think lots of people over-focus on specific sectors: sure houses and college education have gotten more expensive, but clothes, travel and computers have gotten much cheaper. Most of the complaints about "hidden inflation" that I've seen are basically ways of saying 'if you only look at the things that have grown much faster than the inflation average, then it looks like inflation is much greater than average.' Now the question of 'hedonic adjustments' (how do you account for the problem that no amount of 1970 money could buy you an iPhone, or a car as safe and reliable as any car made in 2021) is a tricky one. As I recall from my macro class <mumble mumble> years ago, economists basically introduce fudge factors to account for that. I recall some speculation that the fudge factors in the health care sector (of the US) were systematically wrong, because the population isn't actually getting healthy or living longer as those numbers would suggest.

I over-focus on those sectors because the proportion of my budget that is spent on clothes, travel, computers, iPhones, etc. is a small fraction of that spent on housing, college education, and healthcare. I'm not interested in hearing the CPI tell me how many fewer televisions I can buy this year due to inflation when those other sectors dominate my spending.

  It seems self-evident that the anything for which the cost has gone up will take up a greater proportion of your budget than anything for which the cost has gone down, no matter what the things are. I, for one, own a house and am not currently paying for anyone's college education, so the proportion of my budget going to food and clothing is more relevant to me. Should I say that I'm not interested in hearing people tell me how many fewer students I can send to college when I don't have any students to send? CPI items were picked precisely because they apply to everyone. Raises in housing cost renters more, but increase my net worth as an owner, so it's left out of the CPI. Health care costs in the US are ridiculous, but they're also widely disparate depending on more factors than can be accounted for in a simple measurement like CPI.
