The silent majority didn't always mean what it means today

You know the term "silent majority"? It has been around for a long time, and for most of its history, that phrase meant everyone who has died.

It only entered the political sphere with nixon.

Before that, the silent majority meant the whole body of people who are dead.

There are 20 dead people for every one person living. Does earth have the carrying capacity to hold the 150 billion or so humans to make it "the silent minority" instead?
