Well, obviously plenty.
But it's hard to find a more eloquent illustration of what is totally nuts about the world in 2010 than this little story told in the FT.
Hundreds of football fans heading for the Spain-Germany semifinal - and what a game - on scheduled flights were unable to land in Durban because the airport was clogged up with private jets. The obtrusive celebs included King Juan Carlos of Spain (OK we'll let that pass) and such well known football fans as Paris Hilton and Leonardo di Caprio.
This is the world we live in. We must make way for the rich, whether it's trying to get to a game, or - maybe more important - paying the bill for the crazy ways they tried to get richer when standard productive investment got too boring for them. Maybe people will apathetically let this happen for ever. But if at some point they decide enough is enough, it's going to get ugly.
