death of American culture
I'm only quoting the key relevant portion of your comment so we don't confuse issues here.
Culture is one thing - and yes every social evolution is the death of a previous "culture". Hippies where significantly different than their parents and brought on a completely new way of thinking, just as the white/blue collar workers before them and the industrial revolution before that, and many many new ones to come (right not it's the millennials).
The one constant throughout all of the culture changes in America is the government. The group which is supposed to lay down and enforce the laws of the land so that anyone of any culture can live and thrive.
What we have here, and what i was pointing to is that our Government is taking on a different role, not one of of setting down the laws and frame work which allow for cultural freedom and evolution but rather a Government which is laying down laws in order to influence and Control said culture to make it what it wants.
On the extreme ends of this are total Anarchy (complete lack of government) and Fascism (complete control by the government). While we are not there now, at the bottom of the hill is Fascism and we are driving that way more and more every day, irrespective of the "culture" of the society.
Will we be here tomorrow? yes, in 100 years? yes, in 1000 years? yes. Will we still be free to have our won "culture" that is yet to be seen and is not a guarantee.
