In a ML system, how does labor aquire the tools and facilities they need to do their work? If they pay for it themselves do workers who join later need to compensate the earlier workers?

If bank loans still exist and the workers take one, they are giving some of the value they create to the bank. Again, do future workers compensate past workers who made that sacrifice?
