John Cochrane with an excellent answer to the "Democratic economic establishment".
Their bottom line, really, is that entitlements and deficits are not a problem. They put the blame pretty much entirely on the recently enacted corporate tax cut. (I'm simplifying a bit. As did they, a lot.)
By contrast, we focused on entitlement spending -- Social Security, Medicare, Medicaid, VA, pensions, and social programs -- as the central budget problem, and entitlement reform (not "cut") together with a strong focus on economic growth as the best answer.
