In my experience and especially in the area I inhabit, it tends to be so. That is lower to our middle class tends to be authouritarian/rigid/hierachial. Most people want, at least, at one particular phase of their life, to experience a feeling of signifigance. I don"t know why an authoritarian way of being is embraced. But I know (and I hope I haven't become infected with authouritarianism) is such a defeating, uncolourful and dismissive way to connect with another. There seems to be little room for discussions and free thinking.
