No matter how much evidence you display, no matter how much you offer to show them the truth, they will deny you. You cannot point out all the death, You cannot point out how they will be usurped once they bring the system to power. You cannot explain to them how the system solves none of the issues they complain about on a larger scale.
They want to live a life a luxury while doing nothing, and will never understand that they cannot sustain even a living standard under such a system no matter how much or little work they put in. A system that decimates the value of product and production and decimates most career fields will leave most without work and thus they will hold no value to the system as they cannot or will not produce, and therefore will be eliminated so that they will not have to be provided to.
...with a dash of scorched earth...
At least flat earther have the excuse of science being use for political reasons and of the governement to have lied on serious matters. Thoses communist are the dumbest people you can find. Let me make it clear : the USA are the country on earth that looks the most like karl marx dream. You can associate for whatever reason you want with whoever you want, make your own company, you dont have to pay for whatever the governements wants you to pay (up to you to have healtcare or any other insurance), you have freedom of faith, speech, you can sign any type of contract you want, you vote for almost everyone in charge of the public authority and social management (Damn, you event vote for you judges, your sherif !). You can arm yourself. I mean, just read some early karl marx book. There is nothing like "class privilege" in the USA. It's not like you have to be noble to do anything. Those people are the dumbest people on earth, because they are destroying the very thing they are pretending to defend.
