First, let's start with a clarity statement: Marxism is a bad idea. That said, it's important we understand why it seemed like a good idea at the time, so when we are faced with a similar problem, we don't make the same mistakes.
The primary fault of Marxism as a social philosphy is it requires people to be happy with "enough." People can, and will, discuss means of production and the like, but that's not "why" Marxism happened. While "enough" sounds great when you don't have enough, part of the human experience is to seek better for ourselves and our children. It's why we've accomplished as much as we have. It is simply not in our nature to "settle" for "enough" on the long term so even egalitarian social structures tend to fail as people who have more than enough are held back for the sake of those who don't. Even though the population keeps growing in numbers, we still have the ability to provide more than enough to everyone.
The root cause of Marxism is a present concern for us though. Karl Marx and Friedrich Engels lived in a time of great class disparity. There was little to no opportunity for the common person to improve either their lot, or the lot of their children. You drew your lot at birth and that was it. Karl and Fred called those in the upper class the bourgeoisie, and those in the lower class the proletariat. Germany was a capitalist nation though. The bourgeoisie were not royalty but business owners who used their relative power and influence to keep the proletariat from advancing in ways that might negatively affect their enterprise. The proletariat, under the leadership of Karl and Fred, led a revolt that completely upended this pattern. They decided that individuals could not be trusted to control the means of production without oppressing people, so "the people" or the government would hold it.
As I already mentioned, this solution to the problem of the greed and corruption of the business class does not work. This is evidenced by the fact the two key communist nations in the world, Russia and China, are both very capitolist in their behaviour. Russian oligarchs and the leaders of the Communist Party of Chinese are the new bourgeoisie. The problem we face here in Canada, and even more so in the USA, is the evolution of a new bourgeoisie here as well. It's dramatically clear in the United States where Elon Musk has essentially bought himself a president puppet while he guts the government, starting with departments that have dared to hold back the merchant prince. But before we write this off as an American problem, New Brunswick has long been under the influce of our own merchant royalty. The Irvings and the McCains come to mind. While it would seem that the Irvings have done a better job of walking the line, their influence over government has been exceptionally vast in order to enhance the profit of the company. They get away with it because people who work at the mill don't suffer the same quality of life issues as people who work at, say Walmart. Canadian Walmart workers don't suffer the same degree of hardship as American employees because of Canadian labour laws, but Walmart would lower standards if they could get away with it. Would the Irvings?... I can't really say. I'm hoping they recognize the social contract that exists between them and the people who make them rich.
I have no fear that either the USA or Canada will devolve into Marxism. It requries perfect people to work, and none of us are perfect. However, we've already seen a medical insurance executive executed in the street because of the suffering they cause to turn a profit at the expense of today's prolitariat. The writing may well be on the wall for our neighbours, because Marxism could not have happened without oppression by the bourgeoisie. Whatver form the next socio-economic revolution might take, Trump is going to make it happen by doing what he's doing. That's their cross to bear. It's our cross to both make sure it doesn't happen here... and be prepared to help our neighbours when it really hits the fan, you know, the way Jesus would.
