Just a recap, quoting Francois:
We can roughly subdivide price in three parts: raw materials/capital/tools (the means of production), wages, and surplus (profits, taxes). Wages are obviously reducible to labor, as they are a payment for labor. Surplus is taken from the full product of the worker, and is therefore also reducible to labor. The last category is that of the means of production, but these means of production were obviously produced by someone. The price of any given tool is reducible to the same tripartite division (means/wages/surplus), two-thirds of which is reducible to labor, and one-third being itself a price which is reducible to... and so on and so forth until the first man produced the first tool, an action which is entirely reducible to labor.
Let's continue as usual, presumably with David.
