Humans : about 20% lack empathy. A large part of that group are narcissists, a significant part are sociopaths. In short that 20% can grab control of a country leading to thought control and loss of freedom unless the 80% understand what is at stake and fight for freedom.
That trend toward control by narcissists is strong in the US. Social media sw algorithms is added to the difficulty of keeping freedom.
Why do narcissists folks win in so many countries? Because most folks want to trust their fellow man and filter out the danger signs.
