But doesn't what you're suggesting here go against what a large portion of the population adore, luxury items/home?
I can see the argument that it is superficial but that is the way it is, how do we know peoples mindset/values will change so dramatically?
People's mindsets are a result of their material condition. So before there existed cars, people thought trains were the best form of transportation. Before trains, horses, etc...
So people's mindsets/value systems change according to that material condition and communism is effectively a radical shifting of material conditions brought on by the people themselves.
I'm having trouble understanding what a good management of goods and services would be if there was no money.
The effort/skill/productivity of the workers/community + the fulfillment of the need of those goods and services?
Well, "good management of goods and services" is a subjective phrase. Some would say it's what leads to the most profit (capitalists). Others would say it's what leads to the most enjoyment (utilitarian philosophy). Radical leftists would say that it's what results from working class possession of the means of production.
In other words, "good management" comes as a result of communism and is not something which can be worked towards without it because to do so is idealistic and not materialistic.
If we have no business with the construction of the future or with organizing it for all time, there can still be no doubt about the task confronting us at present: the ruthless criticism of the existing order, ruthless in that it will shrink neither from its own discoveries, nor from conflict with the powers that be.
