I think that at any given point in time those in showbiz were less likely to be what I call "respectable" (that word being used very broadly) than the typical American.So back in 1950 while 2% of "typical" Americans were doing cocaine 8% of those in showbiz were.If 10% of "typical" Americans had been fooling around 40% of showbiz types were.Today,I'd wager that 20% of "typical" Americans are smoking dope and that 80% (or more) of showbiz types are.
Artists have been outsiders since the Romantic era. William Blake (anarchist by today’s standard) and Percy B. Shelley (expelled from Oxford for advocating atheism) weren’t saints either.
