I mean, propaganda is technically a type of meme, isn't it?

Either build something better or shutup, I say. Unless you're a big fan of Tsarist Russia

Both Capitalism and Socialism have room for public and private ownership, the difference is which sector controls the state, large firms, and key industries. The Nordic Countries are dominated by Private Capital, ie it is Capitalist, while the PRC is dominated by Public Ownership, ie it is Socialist.

Communism limits the personal freedoms of the bourgeoisie. All Communism is, is a more developed and global form of Socialism, where the small firms that once were private have all grown into the public sector or collapsed.

Tell me you've never read anything about communism that wasn't written by anti-communists without telling me you've never read anything about communism that wasn't written by anti-communists.

Capitalism rewards greed, thus perpetuating it and entrenching it. So capitalism is the root of our greed epidemic

capitalism is the system whereby greed is raised above all other human impulses though. in most other systems, sure, people can be greedy, but they aren't rewarded for it, and people who aren't naturally greedy don't get pushed and trained to be greedy as the highest aspiration.

Human aspects like greed are not intrinsic to humanity, but created by the material conditions and mechanisms surrounding them, and are thus malleable and expressed in lower or greater degrees in different systems. Capitalism in particular expresses greed as its entire foundation is the relentless accumulation of profit and exansion of markets and commodification for the purposes of private wealth.

lol, so stupid

First, a societal organization outside the Western norm has no bearing on if it will be successful or not. The "middle" has no superior intrinsic characteristics.

Second, we know Socialism works, the PRC is now becoming the de facto world power as the US falls, all while providing dramatic improvements for its people and increasing levels of satisfaction.

What, specifically, doesn't work?

Cool agitprop posters like what OP posted rarely give you a particularly nuanced perspective due to their limited space. The intended effect is to spark conversation, not to beam Marxism into the heads of anyone who sees it.

The USSR did fairly well until liberalizing part of its economy, as well as struggling to recover from the immense cost it paid to win the Eastern Front and beat the Nazis while under the oppression of the Cold War.

The Marxist-Leninist tradition is still carried forward by many states, including the PRC, which is on its way to surpass the US as world superpower.
