If we ignore income distribution and just judge policies according to which has the highest total GDP growth rate this is equivalent to attaching a higher weight to the higher income groups (not just an equal weight). Assuming that the shares of GDP going to each of the five groups are:

            (1) 80%; (2) 10%; (3) 5%; (4) 4%; (5) 1%,

what weights must we attach to the growth rates of each group if G is to be the same as the growth rate of GDP? Do you think it is right that these weights should be used (if only implicitly)?
