I am not sure that's 100% the case. Sure as children and even through college it's easy to make friends, but as we get older, we certainly are exposed to more people and more opportunities if we choose so.

I think the major problem though is due to the way the world is rapidly shifting, and people's utter mental exhaustion, it's easier to sit and do nothing and become a mindless drone to 'the boob tube' or rather your phone than it is to be with your community.

This isn't something new, it's just becoming more evident, especially as there are less and less communities.

Just think about it, you likely live in some sort of apartment, town house, or suburban area, and how well do you know your neighbors? One apartment/house over, two, three? Or maybe just a friendly nod when you pass, but nothing more.
