I know that you didn't say that. Hence the question. I didn't claim you said it. But rb808 sort of did claim this:

...if we relabeled health insurance as a tax, US tax rates would be very high...

Your original comment doesn't appear to be relevant or to add to the conversation to me because VA, DOD, Medicare, and Medicaid spending are already taken into account when computing tax rates. I really don't understand what you are getting at with your original comment. The healthcare expenditures you mentioned are already part of the calculation for the tax rate in the U.S. So there is nothing to add with regard to the programs you mentioned when making the comparison to OECD average tax rates.
