People have tried alternate systems, some have even gone extremely well until they are destroyed by capitalists
The fact of the matter is, the only reason there isn't another system is because capitalists have gone out of their way to destroy every other system that has been tried.
You can't make a fair comparison when you factor in that capitalists already control the world.
Even democratically elected communists were destroyed by the US government.
Undermined by stuffed pockets?
None of the systems I advocated were undermined by stuffed pockets, they were undermined by a capitalist country militaristically destroying a new nation, a capitalist country that has 50 percent of the ENTIRE WORLDS military spending.
That's an important detail not to gloss over.
Revolutionary Catalonia had a wonderful system, the zapatistas have a wonderful system, neither were undermined by what you claim. I'm anti-red fascism, the Soviet union was evil. You just boldly assumed anarchists don't exist, I agree that they were fundamentally doomed, but anarchists have no such fuckups.
Furthermore do you honestly believe capitalism is not susceptible to stuffed pockets??
