I too agree, but I believe the root cause is the scale, speed, complexity and volatility of modern life: there is a great deal of information overload and rapid changes which overwhelm a lot of us.
Humans evolved in environments that usually involved absorbing a limited amount of fairly stable information, and dealing with communities of limited size (say, less than 100?), also fairly stable. Now we have to process thousands of faces (some in person, some through media), millions of pieces of information (news, commercials, trivia, education, business emails, social media feeds) and thousands of different micro-skills (learn the latest feature in smartphones, adapt to your bank changing its electronic banking policies, based on latest research now you need to learn to look for a low-carcinogen version of your favorite food, etc.)
I wonder whether this is what's causing many people to zone out, some to retreat into private shells and a few to resort to senseless armed violence...
