This is a repeat from 2013. What’s amazing is that the Underground Economy, that part which is off the books, has not been studied properly for a solid five years. It may still be 12% of GDP, but we don’t really know.
It’s good to have a lot of money, assuming that not everyone has a lot. Inequality is apparently bad when it gets too big, but it also makes the whole economy possible in small doses. But how much money is really out there, and where is it going? It turns out that this is more complicated – and hidden – than most thought.
