The New Yorker (Sep 2, 2019) reviews yet more recent work on
increasing inequality ("Widening Gyre"). There are many discussions
like this one. What to keep in mind? It’s very complicated! Here is a simple
checklist. Pick any one for your next chat with a political candidate. I stop at ten.
1. Inequality is not to be confused with poverty – although the
zero-sum people seem to think so. Magically double all income and poverty will
almost disappear but inequality will increase. Is this ever spelled out?
2. Almost all the data referenced in these discussions are
snapshots, even if they are repeated snapshots. Real people move in and out of
statistical categories. Only if we track actual people and see how many move up
or move down – and over what time span – do we get a useful picture. Is this
even hinted at?
3. Are the measurable data we have useful? Measure income? Wealth?
Health? Longevity? Happiness? What to count? What can we count?
4. Is consumption inequality getting better or worse? And how
would we know in light of the constant quality improvements of most of what we
consume?
5. Do we care about equality of opportunity or equality of
outcomes?
6. When we see wealth, do we automatically assume ill-gotten gains? If not, why
are we fretting?
7. Are all the inequality discussions feeding off (and feeding)
the unpleasant human propensity to envy?
8. Is fanning the flames of envy a political convenience for
demagogues?
9. Is life unfair in terms of genetic endowment and the inequalities
it bestows?
10, Is there some threshold of inequality where class antagonisms
come into play to stress the political and social arrangements we need to flourish?
ADDED
Here are two very smart economists discussing many of these points. What do they agree on? Better training is a good idea. How do we do that?
