I have just a quick comment to Mr. Howlett.
You raised a number of points on the nature of the underground economy and the difficulty of catching tax cheats. When it comes to tax non-compliance, a lot of it is extremely sophisticated. People who are sheltering money offshore and who have millions of dollars to shelter find expensive ways to be non-compliant.
It's difficult to find. It's difficult to assess. To a degree, in your comment, it sounded like maybe it was easier than it is.
