The Campobello issue has been raised, but Keith McNally is dead wrong if he claims that's one of the poorest places in North America.
Campobello, Parish, New-brunswick - population Statistics and Information | Yourneighborhood.ca
Median income for census families is $44k. Median for lone-parent families is $23k.
Poor? Sure. Poorest in North America? Not by a long shot.
Another interesting statistic. Median family income for Somerset, PA?
$41k. Less than Campobello, and that's not even factoring in that access to Canada's NHS act's as de facto supplemental income.
Kyle was right on that McNally is treating his mother's poverty like a religion. The problem is that religion is a belief system. You can choose to have it or not. Poverty, on the other hand, is a designation. One is poor or not in part due to one's choices, but it's simply not like religion. McNally has access to quite a bit of money and economic opportunity. All the grumpiness and anger in the world doesn't change that.
