I'll just add a comment to that.
I was just talking with biomedical researchers before I came to this meeting. One of them gave an example of how one of his students left Canada and went to the University of Arkansas to do a post-doc, not only because of the amount of money he would be getting but also because of the consistency in that funding over the years. He said it was not comparable at all to what he would get in Canada.
I'll just leave it at that.
