If I burn your house down, is that evidence your house "didn't work" and should never have been built in the first place?

Apparently worked better than the alternative . . .

Saying communism isn't the answer since it will get abused, when your alternative is capitalism, is like saying dating someone in recovery is a bad idea, and that's why you only look for abusive people who are currently drunk.

Just like how capitalism works so well for the U.S. and Canada and many other countries?

Don't you see what's happening around you? I live in Hochelaga, a borough of Montreal, Canada. There are people sleeping in tents in all the parks around my home. There are literal encampments with several people living together. They're freezing to death in the winter and dying of heatstroke in the summer. They're starving. They're sick. They can't afford rent after getting kicked out of their apartments because some rich property baron bought their apartment bloc to flip it. Housing has become a commodity for investment instead of a human right. Same with food. Food banks can't keep up with the surging demand. People are unable to feed themselves because of food inflation. Grocery stores are stocked to the brim, but people are starving because they can't afford it. Our public healthcare system is being gutted and replaced with private clinics and private care that are out of reach for the vast majority of people. And in the U.S. it's even worse! People have to live with preventable health problems, wounds, diseases and die because health care is unaffordable. Even education is out of reach in the U.S. because of how ridiculously expensive it is. How well is it going for us in a capitalist world? Not good at all.

And you're saying it didn't work well for the Soviet Union and China? The Soviet Union initiated the space race. They've kept pace with the rest of the world in terms of technology and innovation. They were one of the most educated people on earth. Everyone was housed and fed and schooled and received the medical care they needed. And China? I'd say it's working pretty fucking well for the world's current superpower. They're leading the world in economy, technology, productivity, progress, and believe it or not, even environmentally. No other nation has planted as much trees as they did or made as much progress in reducing their greenhouse gas emissions as China did. They're putting every other countries to shame.

And forget North Korea. That's not communism.

Hopefully. A wooden box. The kind that gets buried 6 feet under.

Centrism is the enabler of fascism.
