While the ideal of capitalism -- the freedom of capital -- may not be everyone's ideal, its proponents often say that it also leads to the freedom of individuals. I disagree, but it's definitely possible to have a regulated capitalist society with high levels of individual prosperity and freedom (e.g. Denmark).
Well, as a Swede I'm aware of a middle-ground social democracy. But that's unrelated to what I asked about. It wasn't capitalism that made Scandinavia social-democratic. It was through hard fought labour struggles and through socialist ideals that drove the capitalist into far reaching concessions under the threat of revolution.
So that doesn't say anything about how it's unintentional, if anything it just underlines it.
