How can you assume this is what they ment?
What do you mean? How can I assume that when Engles wrote "money will become superfluous" he meant "money will become superfluous?" Or how can I assume that he's talking about a distant ideal rather than an immediate course of action? For the latter, it's literally in the same piece of theory that I linked:
Democracy would be wholly valueless to the proletariat if it were not immediately used as a means for putting through measures directed against private property and ensuring the livelihood of the proletariat. The main measures, emerging as the necessary result of existing relations, are the following:
(vi) Centralization of money and credit in the hands of the state through a national bank with state capital, and the suppression of all private banks and bankers.
That's the short term, immediate measure he's advocating for, in contrast to the long term idea of "money will become superfluous."
You are talking about something else entirely n Communism does not advocate for the loss of personal finances.
I never said anything like that.
Communism isn’t what the u.s government and school systems has told you it is.
Lol? I'm literally citing theory. Where on earth did you get the idea that I'm relying on "what the US government and school systems told me it is?" Of course it isn't that. I'm going off of actual communist theory.
It’s not giving up all your wealth and work to “the state” so it can be evenly distributed.
I never said anything like that.
