I don’t think you are interested in hard data. If you are capable of find your hard data from the commielibs, (the datasets that begin after the oil shock of the early 70’s is the tipoff), then you are perfectly capable of finding it at Heritage or Cato. My guess is that you are afraid to have your assumptions challenged.

If you know it is at Heritage or Cato you should be able to refer it. Interesting you claim to know but provide nothing. Ignorance is bliss!
