Only taxing the rich or bringing back the New Deal perpetuates Capitalism, we are talking about Socialism here, not Social Democracy. In that respect, when we analyze AES states, all have a firm understanding of Marxist theory, showing that it indeed has practical merit.

If you want to get started with theory, I keep an introductory Marxist-Leninist reading list you can check out if you want.

It's the opposite, actually.

The people who talk about "tax the rich" or the New Deal don't actually do anything, they are armchair activists who have no real idea of how they would ever accomplish this outside of pretending the Democratic Party, which constantly opposes them and crushes such ideas, is the vehiclr, and the way to make it happen is complaining on the internet.

Communists know that actually addressing our collective problems is a much more difficult task, nothing less than the overthrow of capitalism, something that would need to survive attempts at cooption by liberal power structures like the aforementioned party. So we build from the ground up, educating one another and developing practice so that we can balance growth, education, and having impact through actions. We go to the meetings, we run the meetings, we teach one another, we organize the protests and marches, we build the strategic mutual aid events, we embed with workers' spaces and unions, we embed with and build from within the marginalized so as to be of them. Communist organizing is adding a part-time job on top of your other obligations.
