Problem: Rich People Have Nowhere to Put Their Money

So here's a mystery: According to the latest numbers from the International Monetary Fund (IMF), the world economy grew 3.1 percent in 2015 and is projected to grow 3.4 percent in 2016. On the world stage, that's a pretty modest rate, but it is growth. And yet at the same time, financial markets started 2016 by panicking as if they expect Armageddon any day now: The S&P 500 has dropped 9 percent this year already, and stock indexes in poorer developing countries have fallen further.
