Well said

Thomas Walkom nicely sums up the Cons' brand of class resentment focused on attacking the benefits of working Canadians:

Today, class resentments have been turned on their head. The focus of anger is not the silk-hatted capitalist but his unionized workers, with their job protection guarantees, their pension plans and their good wages.

Increasingly, in the world of media and popular culture, it is not the rich who are blamed for their excesses but the poor – the undeserving welfare recipient, the shiftless single mother, the employment insurance cheat. Resentment has become a potent tool of the right.
...
The left's resentments were predicated on the notion that if some are privileged, all should be. For all of its problems (and resentment is a difficult force to control), it was at least optimistic. At its best, it encouraged people, through their governments, to improve the lot of those who were hurting.

The new resentment is based on the presumption that if I don't have something, neither should you. Its aim is not to improve anyone's lot but to cut down to a common level of misery those uppity enough to think they deserve better.

It is pessimistic, antithetical to any kind of common action and angrily passive. It rarely focuses on the bigger questions because it assumes that, at high levels of state and economy, nothing can be done, that the best anyone can hope for is to protect his tiny bit of turf from a marauding neighbour.

It is a form of resentment that suits those in charge. For Stephen Harper's Conservatives, it is a most useful passion.
