Glenn Hubbard Explains The Doomsday Scenario That America Will See In 20 Years If There's No Change In Spending

We recently had Glenn Hubbard, dean of the Columbia Graduate School of Business, into discuss his book Balance: The Economics of Great Powers from Ancient Rome to Modern America.

Hubbard's main argument is that the US must reduce its long-term deficit, and that if it's not addressed, then within 20 years the US will see a "doomsday scenario" of virtually no social spending and monstrous taxes.
