The world is so complex, humans are free moral beings, everyone has the right to do what they feel is right and good for them. And sometimes these may not suit our personal preferences. We must learn to live amidst all these facts and still thrive.

Like you rightly stated, most of this social awkwardness are developed from childhood when children are deprived of some of the conditions necessary for their proper social development. Or when they're exposed to conditions that make them live inside their heads, focused only on their own world.
It is becoming more rampant these day and has really become something to be worried about.

I believe the adjustment has to come from both the society at large and then also in the family settings.,
Reduce screen time, expose thees children to real world problems that make them want to ask questions.
Imbibe good morals and teach them to understand the world around them in it's entirety, in its complexities.
