Labor isn’t the source of value. Labor is the source of the whole product, which is what has value, of the firm. Labor is de facto responsible for what is created in production. The employing class is quite literally stealing from workers through their appropriation of the property rights to the produced outputs and the liabilities for the used-up inputs, which together make up the whole product . This appropriation implies a mismatch between legal and de facto responsibility @whitepeopletwitter
