I worked in the poorest postal code in Canada (http://goo.gl/maps/hzKct here's how bad it gets, this intersection is called Wastings and Pain by many), it's a walk in the park compared to the bad neighbourhoods of many US cities. I've never felt like I was in the 3rd world in Canada, there are parts of the US that make you wonder...
We generally take care of our people and don't use the prison system as part of the social safety net to the degree the US does. Ironically, in Montreal in the winter, you pretty much have to kill someone to get sent to jail if you're homeless.
I'm afraid I have to call BS on the ol' "Blame Harper" schtick. The Conservatives, Liberals, and NDP all have exactly the same platforms and would likely be doing exactly the same thing if in power. Canada's political parties have stopped running on the merit of policy and are running purely on the basis of personality. It's really starting to annoy me.
Slightly off topic but I would like to recommend you to read Amusing Ourselves to Death by Neil Postman. In it, he posits that the advent of television is the primary driving force behind image-based politics. It's full of astute observations and generally relevant frameworks in which to discuss these types of effects in society. It was also written in 1985 but everything is even easier to observe now.

Also, it's not so much Canada as Stephen Harper.
