you have are assuming the equation $N/mo = 1 life, is meaningful. I
don't think it is. That equals-sign is in fact a dark hole of
administration and politics. If I could drop a buck or two
in a magic box every day and 3 square meals would appear
in an African's hovel, I probably would do it. If I put a
check in the mail it's going to go through a chain of
questionable custody, and then at the terminus, even ignoring
the interceding problems, the money doesn't just turn into
food. it is invested in various programs of at best
speculative merit. not programs that are sustainable
indefinitely, but attempts to transform or reform that
more often than not fail--not to mention the ones that are
variously corrupt.

in summary. I find this abstract formulation to be of little
to no relevance.
