Let's just put it this way.

Here in the UK, airports are largely privatised. And except for the newest terminals at Heathrow, most airports are a shabby and a bit of a chaotic mess. 

There have been plenty of comments in the UK that privatising the airports was a bad idea. 

Whenever I return to Canada, the airports are clean, bright and airy. Maybe this is because they aren't as busy as those in the UK. But maybe it's also because of the way they are managed.
