Mike Neuenschwander’s Law of Relational Risk
“Contribution to the relationship that is not met proportionally by the other participants is a loss to the contributor.”
is perfectly fine but that it suffers from Asperger’s Syndrome. Relationships are not like accounting. Since there is no reserve currency for relationships it is impossible to balance the books. Since there is no accounting cycle when the books are required to be brought upto date any attempt to balance the books will fail. Their is no consensus about discount rates, they are unregulated. For example if something bad happens to me in a relationship I can, of my own free will, depreciate that into oblivion via forgiveness or I can compound the issue demanding increasing compensation.
Bearing that in mind the rest of his post is all good and useful fun. Mapping economic ideas into the rest of the social sphere is more than fun, it is deeply silly.
