I think one of the larger issues I've seen lately is too many parents not taking the time to actively parent. I see and hear too many stories about parents that are just trying to keep their kids occupied so they can get things done.
For example, my wife was talking to her two best friends the other day about going to the grocery store and how one of our daughters (I have 3) was having a hard time. They asked if we had forgotten to charge the iPads. They mentioned that they can't take their kids anywhere without the iPads, and that not charging them was a rookie mistake. I was flabbergasted. I have a completely different experience taking my kids to the grocery store; I love taking the two older ones, as it gives me a chance to talk to them about where foods come from, how manufacturing works, and just spend time talking with them. That's active parenting.
I'm not saying this is easy, it's not, it takes effort and patience. It would be vastly easier for me to hand them a tablet and ignore them. And I'm not perfect, by any means. Saturday mornings I have a lot of yard work to do, because I was an idiot that bought a house in a forest, and sometimes turn on some cartoons for the kids to watch while I get work done. But, what I try to do is get the kids involved; get them to help rake leaves, pick up branches, help push the lawn mower (they don't really help that much but they sure like to think they do). Once again, it takes effort, but it's 100% worth it. I think too often though I see parents taking the easy way out, rather than making the effort.
In regards to video games, I spend a decent amount of my time to sit and play games WITH them. I know some parents don't enjoy gaming, but that's not what it's about. It's about spending time with your kids doing things they enjoy. I don't like playing with Barbies, but I do it all the time. I really don't like playing Anna and Elsa, and my voice isn't great, but I want to be an active parent. Because when you are actively parenting, you learn so much more about your children, and you can much more easily monitor what and how much the play and watch.
TLDR. Active parenting involves sacrifice, and I think too often people want to take the easy way out. But, it's worth it.
