“Spain’s experience was not unusual or unrepresentative. Lottery winners often do worse in life than if they had bought a losing ticket. The sudden infusion of money acts like a hit of cocaine and distorts behavior in similarly unhealthy ways. Something similar happens to countries on the receiving end of unsolicited financial inflows. Few societies have been able to absorb sudden, large sums of capital from abroad without experiencing soaring debt, asset bubbles, and economic crises. It is an almost inevitable consequence of a rapid and unexpected increase in real purchasing power.”
