As we all listen again and again and once again to Trump, say we need to make America great again, we should consider this:
“The receptivity of the masses is very limited, their intelligence is small, but their power of forgetting is enormous. In consequence of these facts, all effective propaganda must be limited to a very few points and must harp on these in slogans until the last member of the public understands what you want him to understand by your slogan.”
? Adolf Hitler
By the way, in case you don't know it, America is still great!
