Not disagreeing; but for clarity you'd want to refer to generating surplus value rather than value, i.e. net of costs. i.e. if my work can be construed as having created $1M of revenue, but $990,000 of cost (say some low-commission dropship affiliate sales structure, or online payments with a small transaction fee), I've only created $10,000 of surplus value, out of which I can make a case for a different distribution scheme based on an update (read: agitation) of normative values.
