There was a hope then by some people that what we call trickle-down economics would work. That if you made the economy pie bigger, everybody would benefit. Twenty-five years after NAFTA, we know that that is not true. We should have known then that it was not true.
Our economy has not served large fractions of our population. Trump grasped that. And rather than saying, "What have we not done right?" he said, "It's those foreigners. Let's build a wall." He says globalization is unfair to the United States.
People at the top spend less money than those at the bottom so when you have redistribution toward the top, aggregate demand goes down. Unless you intervene, you're going to have a weak economy unless something else happens. That something else could be a bubble. The United States tried a tech bubble and a housing bubble, but those were not sustainable answers. So I view inequality as a fundamental part of our macroeconomic weakness.
In a globally integrated economy, the biggest challenge is to make sure there is adequate global aggregate demand, achieved through spending, when countries like China feel they must save high levels of dollar reserves to protect against international currency volatility.
The crisis was 2008, in 2015 - almost eight years later and the gap between where we would have been and where we are is huge and not closing. The implied unemployment rate is very high, labour force participation is very low, and the increase in wages in the second quarter was the lowest in 25 years. Before this turmoil, the U.S. economy was in better shape than Europe or Canada, but not strong.
The analysis in the era of Ronald Reagan and Margaret Thatcher was that government was interfering with the efficiency of the economy through protectionism, government subsidies, and government ownership. Once the government "got out of the way," private markets would allocate resources efficiently and generate robust growth. Development would simply come.
Negative effects on the economy were covered up with a flood of liquidity from the Fed. That,plus lax regulation, led to a housing bubble, a consumption boom - but we were living on borrowed money. It was inevitable that there would be a day of reckoning, and it has now come. We will be paying the costs "with interest".
