Something those sorts have in common with the youth of today--since the US and its benefits have "always" been here (that is, as long as they've been around), it'll all just somehow work out and "always" be here, no matter what happens.
Children and the pampered rich have never had to go without some version of Daddy being there to rescue them. They operate with a net at all times, so they don't even know that positive fear that comes from knowing your every action has consequences you may have to pay for.
I guess it goes back to where we started - the liberal elites walk around in a fog of mutual understanding and admiration while never bothering with the real world.
I am reminded of a video I saw of Saddam Hussein when he first took power in Iraq. He had brought the State Assembly together and stood in front of them and announced that he had learned that some of them were his enemies. He then read out a list of 50 randomly chosen names from the group of 250, some of them his strong supporters, As each name was called they were taken outside and shot, some with their families. Saddam laughed as each one protested on their way out.
That was his way of instilling fear to assure he would have no enemies, at least none with any power because they would be afraid to identify themselves to others.
That is also the history of Marxists. Some of these liberal elites may get a terrible surprise some day.
