Let us also note that those with 'higher education' are also not only those most inured into every aspect of pro-Establishment orthodoxy, but are generally those with higher incomes and who are more "part of the system", therefore also those with more to lose by changing the status-quo, no matter how beneficial or self-evidently positive or good those changes may be.  

Just think, for example, of the district attorney who makes his living by sentencing non-violent drug users to prison, or the prison warden whose financial bottom line is enhanced through the incarceration of non-violent drug users, or the policeman or DEA agent whose career consists of tracking down and apprehending those same people.  Do you really think that ANY of them are interested in, or supportive of, the relaxation of drug laws in the USA?  And I could broaden this argument almost infinitely to other so-called "highly educated" individuals, each of whom is dependent upon the rigid status-quo.
