"Capital must make enough profit to attract investors, and wants to make as much more than that minimum as it can. Labor must make a living, and wants as much more than the minimum as it can get. Between those two minima lies the line of dispute, which is the locus of all points of reasonable and practicable settlement. Somewhere on that line lies a point, which can be computed from the Law of Diminishing Returns as base, at which Capital's net profit, Labor's net annual income, and the public's benefit, will all three combine to produce the maximum summated good."
