I think it's the 60s, as the drumbeat of Vietnam was approaching, sparked by the assassination of both Kennedy brothers. The so-called End of Innocence for America, the Killing of Camelot. It's when we learned that dissent on even the highest pulpit will be silenced.
We were warned before then by Eisenhower in his final Presidential address, but the tail end of the 60s was likely when Americans started to realize that we could not stop the rush. Endless money and inscrutable power will be forever intertwined, from the Medici's silent rule of Italy to now, where a few million dollars donated to the policeman's union by JP Morgan can buy the emptying of Zuccotti park and put the kibosh on the months-long Occupy movement.
While the connection between the "bribe" and the deed are speculation at best, there is no doubt that bankers made the donation and announced just a month into OWS. It was actually JP Morgan Chase that donated 4.6 million[1] (I've amended my comment to reflect that).
