Is the united states of America really a communist country and most of the citizens don't know it?

First they think the progressives and some socialists falsely calling themselves "liberal" want to do that and some of them do. Second they are exaggerating of course. The US is already a progressive society with lots of controls on business, but progressives want it to have a lot more and socialists want wealth redistributed.

There are relatively few communists today so the drive from the left is truly for more progressive policies and in some cases for more socialist ones.

With all due respect, you've just shown your ignorance on economic issues. There is NO SUCH THING as "trickle down economics". You can search the whole world and not find a single trckle-down economist, because there is NONE.

Now, to your main point. Even now in America, with its vast number of economic illiterates, the terms 'socialism' and 'communism' might scare people off. So, those intent on instituting such a system, have been doing it a little bit at a time...piecemeal, in other words...but whether it's done in one full swoop or a little at a time, you wind up with the same thing.

A planned economy that can only operate through a form of dictatorship. This has happened over and over again. Read F.A.Hayek's THE ROAD TO SERDOM and his other book THE FATAL CONCEIT: THE ERRORS OF SOCIALISM.

This is a serious subject, scores of millions have paid with trheir lives worldwide because they didn't understand the inherent dangers, and the inevitable rule by dictatorship of socialist economics...whether you use that particular word or not.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
