Awhile back I think Doug on his show had a beef with CBO growth rates---too low for too long, and that such inputs are left unexamined.
This from Mauldin's newsletter which is influential, and quotes big money managers:
"...an influential 2010 historical study of high-debt-level economies around the world, by Professors Kenneth Rogoff and Carmen Reinhart, that concluded that when a country’s gross government debt rises above 90% of GDP, 'median growth rates fall by one percent, and average growth falls considerably more.'"
Are Rogoff/Reinhart at or near the heart of the "low growth is here to stay" idea?
