I work with a group of coworkers that are a little less than half my age, 1 or 2 years out of college. They are all excellent.

Of course they goof off and sometimes make inexperienced decisions like every kid their age (ex. thinking that sharing a 1 bedroom apt with a stranger is a good idea, even though the bathroom is in the only bedroom). But I did the same things at their age, but they are surprisingly professional and make mature decisions at work. If I didn't spend a lot of time with them and only spent time with people my age, I probably would think the same thing, like my parents probably thought of me and my friends. It's the fallacy of age, and it happens every generation.

My wife, on the other hand, works with someone who is is the epitome of the article. Self-entitled, bratty, arrogant, etc. But I think this is more the case of the upbringing and not necessarily to do with the generation.

I think they're going to be just fine.
