Inflation remains low? Seriously, I have no idea how they are computing that rate when asparagus is $4.99/pound these days. It seems like low rates feed the housing bubble nicely, and if housing costs were more adequately represented in the CPI, it would be much higher.
Housing costs are reflected in CPI, as imputed rent. I couldn't find the exact weights with a quick search, but IIRC housing costs are around a quarter of the basket. Asparagus is less than that.
