Two things. First, I’m not pro-communist. I’m anti capitalist. There’s a subtle but really important difference. I can be against one system without being for another.

Secondly, I am able to apply the failings of capitalism to the system as a whole, by looking at its roots. I’m not from the USA and I’m not only looking at US capitalism. Capitalism is inherently exploitative, favouring people who own interest-accruing property over people who work. It favours the amassing of wealth, which necessarily comes at the cost of other people’s well-being and success. We see the outcome of this is that the people who are most rewarded by the system are the most inhumane, to the point where the top earners are outright sociopaths. The people who suffer are those who just try to get along. All of this is universal across all countries and interpretations of capitalism. The system rewards greed and unscrupulousness, and punishes compassion. It’s destructive at this stage because it is being allowed to run rampant, unchecked by any common sense. It’s ok in small doses, but the neoliberal consensus is global.

Lol, right. So let’s break down this down since Communism has miserably failed every test and attempt it’s attempt at being used …

Interesting you should bring this up, because capitalism has failed every time, too. Communism has been tried, what three times? And capitalism about 300. So communism is winning on this front, in fact it’s 100 times more successful by comparison.

Yes, because capitalism is the dominant power structure in the world, and communism is one of its anathemas, communism has been suppressed and demonised at every opportunity. This is a historical fact. I don’t know if communism would work under different circumstances, but I’m certain it can’t work under the circumstances in which we have found ourselves since the second world war, circumstances which are hostile to communism. There’s a good chance that had it gone the other way, I would be here claiming communism is the root cause of most societal problems.
Capitalism is not intrinsically better than communism when you count oppression and unnecessary suffering and death as the metric.
Stanning for the status quo while we descend into late stage capitalism and people are being stripped of their economic and social freedoms like never before is a pretty awful stance. Look around you, the world is fucked. And the world is capitalist. The system does not work. Unless you’re a billionaire, you should have quite a lot to complain about.

Capitalism is the root cause of a whole heap of major problems. Almost all of them in fact. I suppose you could go one further and settle on greed as the cause. But since capitalism is institutionalised greed, it still wouldn’t excuse capitalism even if you did.
