Work Ethics and Morals

Is it me, or do the younger generations have no or very little work ethics and morals? I work in an office with 18 other people. Of those, only 3 others are above 40. I am the oldest of the group at age 56. Most are in their early to mid-20's and a couple like the branch manager are 30 to 31. It seems they can never get to work on time, never take just an hour's lunch, find nothing wrong coming into the office still having a buzz from their drinking party the night before, etc. Our manager had a family emergency and has been out of the office for 8 days. In those 8 days, 2 have been fighting as to who's in charge. The entire office has had a shitty attitude with lots of fighting and yelling going on. It's like working with 5 yr olds, not adults. They are all into what you own .. material things and looks are far more important than friends, family, health, etc. It's such a "Me" oriented generation. There is no respect for others, no consideration of what their actions or words might do to someone else. It scares me when I think of what society is going to be like in the next few years.
