Generation Y

I was reading this book about Generation Y.  This book was more focused on what Gen Ys buy and why.  However, it did talk about dating and relationships.  Maybe this not meeting desirable guys is an age thing?  It said many Gen Ys don't know how to date because dating doesn't really exist.  Instead people "hang out" in groups and "hookup."  It also said Gen Y was brought up believing they could and would have anything they want = no settling.
