Earlier quoted context omitted.
What exactly is the historical basis that it's unintended? The origins of capitalism are hardly a display of democratic prowess.
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).
So that doesn't say anything about how it's unintentional, if anything it just underlines it.
