As I said, I don't think it's a simple zero-sum.... There are certainly things that could be done in-house by public servants. Certainly managing outside suppliers more effectively is one of them.
There's no right mix. Right now, as a ballpark, the government spends something around $50 billion on its public service and $15 billion on contractors. That could be a little more or less on both sides. It's always going to be a mix and that's a judgment call that has to be exercised by governments.
