In his conclusion of this extremely robust manual for creating a solidarity economy, Luis Razeto Migliaro takes on the tricky question of deciding how much workers should be paid. For one thing, remuneration is not a fixed amount. It’s a percentage of the surplus produced. But then how much should workers be paid? Should workers be all paid the same? Paid according to need? Paid according to work? Migliaro offers pros and cons for each question. Lastly the criteria he suggests is that workers should make this decision by focusing on justice, efficiency or solidarity.
