That is the welcome burden facing Roman Abramovich, Britain’s richest man and owner of the Chelsea football club, who yesterday essentially doubled his fortune – making $13.1 billion when he sold his share in Sibneft. The Financial Times asks its readers for suggestions on how he should spend this new bounty. As I write this, only one response so far, but it was nice to see that it was in favor of alleviating poverty - not buying up all of the Serie A and NBA as well. I think we know what Jeffrey Sachs would say. What would you do?
