Speaking of nepotism in India, here's my 2003 article in The National Interest, "Revolutionary Nepotism," surveying the global resurgence of dynasticism. It would be interesting to update it to see which way trends have gone over the last decade.
One of the things that got me interested in the topic was the growth of dynasticism among baseball players: the best National Leaguer and the best American Leaguer of the 1990s were, arguably, Barry Bonds and Ken Griffey Jr., whose fathers I vividly recalled. (I watched Bobby Bonds's first major league game in 1968 on TV, and he hit a grand slam homer to beat my Dodgers.) Before the late 20th Century, there just weren't a lot of examples in baseball history of superstars who were the sons of all-stars or vice-versa. So, one question would be whether this trend has continued in baseball over the last decade.
