Dear Pete.
Please recall that Mr. Harper & Company were moving toward budget surpluses, therefore they would not need to be creating more ways to squeeze taxes from the people.
The problem is on the spending side of the ledger, the Liberals are happy to buy votes with reckless spending, all the while telling the populace that it is the evil rich who should pay to make their life better.  Which is okay to a point, but we are going well past that point...
