I don’t hold out much hope for America. If Trump is elected we may escape our fate— for a while. But I don’t expect that my grandchildren will live in an America that we once knew.
Sorry, but the US has never been the "America that we once knew."
For examples, my grandparents grew up before automobiles, much less airplanes, but lived long enough to see men walking on the moon.
Thank God, they died long before men walked into women's restrooms, but that's a different matter.
Point is: the US has constantly changed, throughout our history, never the same, never "the America that we once knew".
Granted, not every change has been for the better.
