This chart shows the Urban Consumer Price Index for cars divided by the total CPI since 1980. Thirty years of falling car prices ended with the great recession. Fire up your insta-theories(tm).
Update: I think I understand this now. Growth in the medical sector dominates the total CPI. If you divide any other segment of the CPI by the total CPI you will get a chart that’s similar to this one, i.e. one that shows that below trend growth for that segment. Nothing can compete with medical for such growth.
