By Bess Levin 1 Comment / / Jun 19, 2015 at 4:48 PM Senator Rand Paul of Kentucky has appointed Mark Spitznagel, the hedge fund manager, as a senior economic adviser as he seeks the Republican presidential nomination…In addition to limiting the role of the government in the markets, Mr. Spitznagel has had other ideas on how to bolster the economy. Last year, he brought 18 goats to a blighted neighborhood in Detroit to help clean it up. Part of his plan was to employ local residents to take care of the goats, which he hoped to increase to 60 in total. But the plan was thwarted by city officials who argued local laws prohibited animals from grazing on city property. Within 48 hours the goats were back on a truck, destined for the butcher.
