The good negotiators set their objectives interms of range, which they might formulate as "We hope to get two dollars, but if we get one dollar and fifty, it will be all right."
Every good on the market exchanges interms of relevant quantitative units: we trade in "bushels" of wheat; "packs" of 20 cigarettes; "a pair" of shoelaces; one TV set; etc.
But since I feel that you are men of genuine good will and that your criticisms are sincerely set forth, I want to try to answer your statements in what I hope will be patient and reasonable terms.
