I feel like I am really lucky to have grown up when I did. We always had dinner as a family in the evening and on the weekends unless I was doing something with friends. We also didn't have to worry about as many of the distractions that people have today. My dad worked in a factory, so when he clocked out for the day he was done. We didn't have to share our time with him and work. My mom was a stay at home mom, so that was another benefit. The world today is hard for sure. It takes a lot more effort and commitment I think.
There's lot of reasons families don't have what you described and a lot of reasons why...those reasons don't negate the need for a strong family unit though I think.
Yes, that is a good point.
