Going down that same ol' path again

I don't get it today!  After all the debate and controversy about the Commonwealth Games, here we go again down that same ol' path for the World Cup.  Commentators are saying yet again that the facilities wont be finished in time.  Why is so much money being spent on these events and people in these very same countries are starving and homeless?  and what happens to these facilities when the 'big event' is over?  just questions for silly people like me!  Ah well
