It makes me sad we've reached a state when nonsense like the above gets modded insightful. Let's go through the points...
That is an *amazingly* accurate depiction of what has actually happened, historically, as communist regimes attained power by upselling the benefits of cooperation and then ended in genocide and bloody civil war. You can read all about that here [wikipedia.org].
You're likely referring to the soviet union or china, neither of which are socialist. They call themselves socialist as a PR move, while they are in fact oligarchies. Their failures and atrocities are not the result of socialism
The exact same, but even worse, because those with all the power get complete control over everyone's lives, deciding who will do what jobs, how much they will produce, and who will then get to receive what they have produced.
You again confuse totalitarianism with socialism. They are nowhere near the same thing.
It invariably devolves into totalitarianism by logical necessity.
No, they didn't devolve in to totalitarianism - they were totalitarian power grabs from day one that called themselves socialism as a PR move. Meanwhile look at the US during WWI & WWII, during both periods socialism was the de facto state of government in the US. We simply didn't *call* it socialism. It was called patriotism. Meanwhile the democratically elected government controlled production and distribution at all levels to maximize the war efforts. Assets and patents were seized at necessary for the greater good.
So in one case, the need for money is the motivator, and in the other case, the end of a loaded rifle is the motivator.
We know (and have even discussed on slashdot for years) that this is not true. Money motivates only so far. And your loaded rifle has nothing to do with socialism, you have YET AGAIN confused it with totalitarianism.
Under capitalism, however, you are free to choose your own line of work, choose your own employer, and choose for yourself how you will spend the money.
You forgot the sarcasm tags in that note. None of those things are under your control in a capitalistic society. Your options for work are dictated by what employers need. Your choice of employer is dictated by your allegiance to their political will. You have little practical choice on your expenses beyond 'Would you like your McMansion in red or blue?' Sure, a portion of your income is allotted to the circus of your choice, but the bulk are funneled in to basic necessities like food, shelter, and medical - all of which are priced as absolutely high as possible. You can't opt out. Opting out just means you die under a bridge.
Your biggest failure is this - you perceive capitalism and socialism as competing models, likely due to your indoctrination. They are not. They are two tools available for a society to plan their collective efforts. Advocating one over the other is just silly, like advocating for saws over hammers, or nails over glue. A sane builder uses all tools available to them, and a sane society should do the same.
