I've been reading Capital off and on for months and this is a seemingly pretty important difference that I don't understand. Is there a difference between surplus labor and profit, and if so, what is it? Any explanations, links, or chapters in Capital I should check out are appreciated.
Yes, to yer first insight, though I don't understand yer second insight... usually rate of surplus value increases, by increasing surplus product, depressing variable capital (wages) or both
do you know where the rates of surplus value and profit differ, just to ask? (hint: wages vs total Capital)
