Anarchism, in this question, refers to anti-capitalist anarchism.
In capitalism, the general idea is that the profits belong to the capitalists because they provide the capital for the resources and the means of production. Example:. someone starts a factory, but they have to use their own money (or borrowed money) to get the factory started, thus earning them the right to the profits.
A more contemporary example might be shareholders investing their money into a company, allowing them to receive a portion of the profits.
Now, it's quite obvious that in an anarchist society, workers collectively own the means of production and the resources necessary to produce. This gives them the right to share the profits among themselves.
My question is: In an anarchist society, who would provide the capital for a new business that is collectively owned by workers?
Surely it is impractical to assume that workers can always, collectively, raise the money required for starting a new business. After all, if someone has an idea, it's hard to get a huge amount of people to support it and risk their personal capital and start working for that business.
A second question: what if a syndicate starts failing and making a loss? Do the workers get less money, do they work for nothing or do they just leave the business without paying what they owe?
AnCaps can answer, but I don't think they can add much more than "that's what I was thinking". I'd really like an answer to this, if there is one.
