I think so. It's sad, but it's quite true. We can blame parenting, society, etc the list goes on and on, and the reality is it's all of it.
The other day I was in the movie theater, there was a little kid that sat two seats away from me. He looked about 3 or 4, and he was just being obnoxious and loud getting in and out of his seat. The parents just let the kid go do his thing. There were some quiet parts of the movie where I couldn't hear because of the kid. When I was a kid, if I had acted out like that, my mom would have smacked me and told me to sit down and be quiet. Sure the kid is young, but if they aren't disciplined young, then when will they listen? There are too many parents who don't know how to be parents.
A few weeks ago, I had to deal with some really obnoxious customers at the restaurant where I work. They came in like we owed them something, complained about this and that and at the end one of them left without paying. My manager told me to not go out and chase after them because it'll be a waste of my time and effort. Worst part? The one who left had a kid with her, now the kid is going to learn from her mother that you can get free stuff by behaving like trash.
I do see a few good eggs from time to time, but the rotten ones just outnumber the good ones all the time. It's sad. Not enough good examples floating around.
