This is the problem socialists have, which is, why has it not worked before
As she writes
Firstly, Luxemburg held that the mass strike “is and will remain a powerful weapon of workers’ struggle,” but went on to stress that it was “only that, a weapon, whose use and effectiveness always depend on the environment, the given conditions, and the moment of struggle.” Secondly, she held that the Russian proletariat was “not setting itself utopian or unreachable goals, like the immediate realization of socialism: the only possible and historically necessary goal is to establish a democratic republic and an eight-hour workday.”
In Luxemburg’s view, socialism could not be on the immediate agenda in Russia for two main reasons: the working class at the time constituted only a small minority of the populace of the Russian Empire (less than 15 percent), and it was impossible for socialism to exist in a single country:
The disconnect is that in order for socialism to have a remote chance of working, a government needs to be set up to oversee each and every financial transaction, and then redistribute the money as they see fit. This requires the government to have an inordinate amount of power over the populace, which is why it has been so popular with despots over the years as more have been murdered by Marxism than by any other ideology, hundreds of millions more.
Man's nature is corrupt as it seeks power, secures power, and then seeks more power. There is no underlying concern for "the workers". There is no underlying concern for "democracy".
In fact, if you do away with a free economy, what freedoms do you really have anyway?
But socialists are undaunted preaching that it will somehow work, this time.
