Feudalism was terrible, but at the time it was better than everything else that had been tried. That does not mean it'd have been valid to conclude "maybe it's not so terrible".
I don't actually think it's very interesting whether or not people think socialism or communism can work.
I think it's more interesting why people think capitalism can survive, and why they think capitalism is somehow unique in not having failure mode that will eventually end it.
