@mike_hales Hi Mike! Hope all is well.
This is from a passage in which Razeto is challenging the idea that solidarity is external to economy and can only supplement or correct injustices through redistribution. Razeto's idea is production with solidarity, distribution with solidarity,
investment with solidarity, etc. Like Marx in the Grundrisse, Razeto sees solidarity at the heart of capitalist economy -- radically othered and subordinated -- but indispensable and full of potential.
