Communism, boiled down.

Communism/Socialism is not based in envy?
What is it then?
Guy invents something or a way of doing his/her work so that they have more free time to work on other things and are more productive.
They have excess.
Their neighbors say "heeeyyyyy look at what you have and I'm still working".
So person 1 sells excess or invention/method so they can have excess time/work too.
Later they invent more, but the others do not.
Eventually, and this DOES always happen and is when Communism/Socialism happens.
The neighbors say... "wait a min." they have the stuff, their land, just like us, and our money because they keep selling stuff to us... that's not fair!!". (they are incapable of seeing that... no, they refuse to see that they choose to buy the products, inventions, and sell what they do to person one and did so on day 1, have yet to build, invent, etc, anything on their own to reduce their work or create anyting new to open new demand).
Envy, all of it.
BTW... on another point that will come-up.
There is not one nation on this planet that cannot stop buying from the US tomorrow.
Cuba has only two embargoes, none of the other hundreds of nations deal with them because their system is corrupt and sucks, like all of Communism and Socialism. If that was not the case they would be fine without us.
