I have just spent three years at uni with a bunch of 18-25 year old's and for some of them, some of what what you have said op holds completely true, particularly this Will they expect to have and do everything with minimal effort because everything has been provided for them.
I have sat with them as they tantrumed (and I do mean tantrumed like a 2 year old), over being expected to meet deadlines, having to do extra work, the canteen running out of what they were expecting for lunch, being asked for money to go on trips, oh god the list would be endless. Genuinely horrified and outraged that stuff is expected of them, that they had responsibilities that no-one but them was accountable for, and that there were no exceptions or ways to get out of it.
The best was that Daddy was refusing to bankroll a HOUSE (as in buy one outright) on completion of her degree, where on earth would she live? 
Nothing seems to be experienced first hand, just filmed for later perusal and nothing really happened until it has been instagrammed.
Mobile's are constantly scrolled though, through every conversation, with other students, lecturers, everywhere, All. The. Time.
Total inability to concentrate.
Huge lack of connection with the wider world, ('but how does this affect me?').
Oh and also not being able to go for a drink after a long day because their phone was out of charge wtaf? Not for any kind of emergency, just, you know, incase. This happened several times with different people, though once it was rectified by nipping to the apple stone to buy a new charger and then plugging the phone in in the pub.
That said a proportion of them were not like that at all and were how I would expect students to be, engaged, passionate, wanting to change the world and realising that that would start with a change in them, not by 'liking' something on facebook, feck all interest in phones or selfies or self absorption.
Sorry long and ranty, maybe I needed to get that off my chest after three years
