The different dimensions (diiferent kinds of hierachies)
have no common measure. All that links them is the
income, rep. probably of getting certain amounts of income.
1) Is the measure of hierarchy not (often) only ordinal?
There is always a past ? rank, etc.
2) The income would establish a simple
substitution relation between the various dimensions
of it were deterministic.
As it is, we get different roles of substitution for
the probability of more than x income,
for each x another ? in principle.
