While we cannot change what the US is doing, we can appreciate that their society is dominated by a capital class that cares more about the profits from guns than the children of other classes there.
I don't really think that "profits" from gun sales are really why the U.S. insists on their right to 100-round magazines, "cop killer" rounds and bump stocks. I very much doubt that the vast majority of supporters of laissez-faire gun laws own stock in Smith and Wesson. This is just a huge, strange thing for them. Maybe it was "taming the west". Maybe it was literally originating from a revolution against an untrustworthy government. Maybe it was some dumbass "Founding Fathers" choosing to protect every citizen's right to own a single-shot, muzzle-loading, black-powder musket that could seriously wound a rabbit at 30 yards. But the closest Canadian equivalent would be our government proposing to ban hockey.
