"The Mondragón co-ops avoid this degeneration by separating ownership, which varies in value, from voting, which is strictly equal. Instead of buying stock, new applicants advance labor to pay the membership fee. Roughly a year's salary, this loan by members starts an "individual capital account" (ICA) to which monthly and year-end profits and losses are credited or debited. (Thomas & Logan 1982, p. 136) Unlike stock shares, ICAs are neither accumulable nor sellable and carry only one vote. Being both individually recoupable upon leaving yet available meanwhile for collective investment, they constitute a sort of bank inside each co-op. Rights attach solely to membership and terminate when members retire or leave. There being no non-worker owners, co-ops remain whole solely in the hands of their active workforces, avoiding the Rochdale error. A co-op could be sold, but only by a hard-to-muster two-thirds of a general assembly vote, and this has never happened.
