You prefer an individualized, subjective definition of fair that is different from person to person? How does the term "fair" have any meaning if there is no objective standard of measure as to what constitutes "fair". Is fair/unfair a feeling or a fact? if its a fact then once all the emotional overtones are removed anyone can determine what is or is not fair based on a pre-determined set of criteria.
Nice work.
All of the above. All elements are weighed to appraise fair value --- before the proposal.
The proposal always exceeds fair value by any measure. It can be accepted, rejected, or countered, unless it ventures beyond some degree of wrath, greed, sloth, pride, lust, envy, or gluttony. Just ask the Secret Service.
Yes, both parties have ventured beyond a degree of excess. At one stage there was tolerable value nearer to fair in the mind of each party. But not absolute fair value, considering all the elements you mention. Absolutes don't exist. Especially absolute fair in a proposal. But because of those pesky deadly sins, neither party would show their hand.
Your weakness (east and west) is that you fail to define your measure of value within your profession and thus cannot define your strength to succeed.
