2003-06-28 D&G- Rent and capital p441 """ Ground rent homogenizes, equalizes different conditions of productivity by linking the excess of the highest conditions of productivity over the lowest to a landowner: since the price (profit included) is established on the basis of the least productive land, rent taps the surplus profit accruing to the best lands; it taps "the difference between the product of two equal amounts of capital and labour." """ p443 [a distinction is drawn between . Direct comparison of lands, differential rent; . Monopolistic appropriation of land, absolute rend.] p444 """ Land is stockpiled territory, the tool is stockpiled activity, and money is stockpiled exchange. """ [a few other things. . Money comes from the tax paid by the poorest. . Why is rent sometimes relative and sometimes absolute? Why is sometimes something I gave sold and I get something back, and sometimes not? Why is the amount of money on both sides the same, isn't there is disparity of value? Money is relative all over the place, from location and context and which side of the transaction you're on, but it's a value none-the-less. It has the same failures as manufactured reputation systems.]
