Whats wrong with the early 20 somethings

A couple days ago I spent most of my day dealing with the craziness of the high maintenance, self-absorbed, and arrogant early 20 somethings. These "young adults" have been brought up thinking that they are always correct, never do anything wrong, and that things need to be changed to fit their needs. Holy F..k
Some how the generation that was born during the free love and LSD era grew up and started having kids and decided to teach their children they don't have to listen to anyone, everyone is a winner and if you put your mind to it you can do anything.
Now don't get me wrong there are a lot of early 20 somethings that have a good head on their shoulders, know how to treat people and how to work hard. Those are usually the ones that have older siblings and parents that are in or around the baby boomer gen. But I'm sorry to say the strong majority I've dealt with have this "everything is owed to me" mentality and that they don't have to put the work in to get ahead in life it should be just given to them, because.
Well I think it's time that we start deprogramming them so they realize that their are losers in life, just because you think you can do something doesn't mean you can and you have to listen to authority at the workplace and any where else you're not in charge. Also you may have an opinion but that doesn't mean you get to give it or anyone well listen to it and just because you want something doesn't mean you get to have it. To you "young adults" time to grow up at your age throwing tantrum doesn't work anymore...
