Sweet, I'll fiddle with things a bit given the suggestions.

As for banks, I honestly don't know enough about them and their operation to reorganize them. I imagine they'd be nationalized and subjected to regulation, but would otherwise operate much as they would in a normal market. While personal investment coops would be powerful enough to promote new business, I doubt they could finance large business endeavors. Banks holding accounts, charging interest, and offering loans seems necessary. The government would be the primary profiteer from interest on loans.

That said, the debt of a company or coop would be the responsibility of its workers in such a system. Perhaps if a debt is untenable interest could be set to zero?

Banks are the hard part. I'll probably think on it a bit more and work on the sheet. In any case there's going to be a staunchly market socialist Netherlands out and about.
