    Comparing the US and Sweden, it's also useful to know that the proportion of refugees accepted by these two countries is wildly different. Sweden has historically taken in many ref…

    The argument is that rate of return only regresses to the mean if you diversify. It's like saying "I hold stock in a single company, so if I hold long enough, my return will averag…
