First, there are innumerable economic studies.
Jack Mintz recently did studies supporting the fact that lowering the Canadian income tax rate does generate jobs. As for the comment on the cash that's retained by corporations, they'll invest the cash when they have good opportunities for investing it. The best thing the government can do is create the opportunities for these businesses to make investments. We're in a global competitive environment, and the companies will invest the money where they think the best opportunities are. In this unstable, economic time, I think they're being very conservative about it. Trying to do anything to force them to put money in places they don't think are appropriate is not the right approach.
