I don't particularly think the age and years matter as much as "human nature" matters. It is our innate nature to corrupt, to seize power, and to control. The price of freedom is eternal vigilance.
Germany was a great example b/c the NAZI took over was applauded and supported by the people. People think that USA would NEVER be that easily fooled or going down that road yet this past election was challenged heavily by socialists (Bernie) and communist (Hillary). Never in my lifetime had I ever thought Americans would support socialism and communism.
But then again, never had I imagined Americans would eat tidepod or be confused about gender.
