It is fear... fear of ostracism, fear of loneliness.
The masses fear their own company so much so, that they will throw themselves into any relationship/group/community, even if it's toxic af, just to "fit in". Ostracism doesn't affect psychopaths at all, thus they tend to become "leaders"; though for us, it's like being shot.
But whoever isn't out everyday, conquering some fear, has not yet learnt the secret of life. Fear defeats more people than any one thing.
Until the individual learns to pay regular visits to themselves, to recognise the value of their own unique and transient existence, loneliness will no longer be a problem, and so they won't just go looking out for any company, but genuine company.
