Partly true. While SAVAK was wicked, the educated pushed for a pre-Islamic identity that emphasized Persian heritage and secularity. This greatly disturbed an element of the population. There was a real effort to "westernize". Women right's were fundamentally expanded and many of those reforms hold(voting, marriage rights, the right to education). There was also a huge distinction between rural advancement vs urban advancement with the city people earning much, much more. My take is that the 60s/70s were much more progressive than the post Islamic Revolution environment. That's the Iran the youth want to return to. Secularity and individual rights within a welfare state.
