affirming the economic consensus that complete economic equality is inefficient.
What is the Ideal Economic Pie?
Kareen Movsesyan

In other words, econ. equality impairs growth and GDP.

Possibly, but only possibly, that reasoning might make sense in the aggregate. But the reality of our economic situation is that there are contemporaneously iwthin our society several economies, which can be though of as gearings.

The aggregate may expand and bring greater riches, but in our present system this bounty is generally shared mostly among the affluent.

The super-affluent’s gearing seldom connects with the Walmart employee’s.

The theory of efficiency represented here speaks to growth from a purely aggregate perspective and says nothing about the separate gearings.

I am simplifying, but this is one reason why in terms of the utilitarian principle trickle-down is always unsuccessful in creating balance.
