An item worthy of note in regards to the phenomena surrounding “occupy” is the unionization movements in the U.S. during the 1930’s.
[Paraphrasing] The majority of unionization that came about in the 1930’s did not come about due to labor actually voting for or against unionization. The majority of unionization came about by coercion by unions [including occupying the physical firm]. The majority of “unionization” in the 1930’s, was in fact, the firm merely accepting a particular union which exercised coercive means of varying nefarious nature. Hence the firm accepted the union as the representative of the current workers, not by vote, but by coercive means exogenous to open voting by labor. - FDR’s Folly, How Roosevelt and His New Deal Prolonged the Great Depression, Jim Powell, pages 187 - 206.
