I recall very similar studies and articles 40 years ago.
I don't mean to hijack the thread, however, on a related note; have you seen Brit Humes "Conservatism: Right All Along"?
It is like watching todays news in black and white with actors from the 40s and 50s. The more things change, the more they repeat themselves. Same with the 'oil is gonna run out in 10 years' mimi. This crap is aimed at the dumbed down yutes with little knowledge of history and even less motivation to find answers for themselves.
