Groceries are actually one of the things which have not been getting more expensive over time. The national calculated inflation rate is such that $100 in 1983 is equivalent in purchasing power to $253.02 in 2018. In the bay area, "food at home" (in linked document) is found to cost 252% what it did in 1982-84. https://www.bls.gov/regions/west/news-release/2018/pdf/consumerpriceindex_sanfrancisco_20180510.pdf https://www.bls.gov/regions/west/news-release/2018/pdf/consu... This document interestingly shows that motor vehicles have been getting cheaper in the bay area, even before adjusting for inflation.
