Well, I do know why. At least my theory is, if you look at the history of the Patented Medicine Prices Review Board, it was established by Brian Mulroney's government as a gift to the drug companies. The rationale at the time was that if we gave them higher prices, they would give us research in return. They promised in that deal under the Mulroney government, when the Patented Medicine Prices Review Board was set up, to invest 10% of sales revenue in R and D. Now we're down to about 5%. They never met their promise, so we should not be rewarding their price.
