Barro
presents a claim that seems self-evidently true: partisans and
ideologues should be prepared to correct their errors. In this case, he
points to monetary policy: Republicans are simply and demonstrably
incorrect, "and if they figured that out," they'd adopt different
policies.
But therein lies the rub. They really wouldn't.
Long-time readers may recall that I've been kicking around this thesis
for many years
(maybe I'll write a book about it someday), because I think the
asymmetry between the two major competing governing philosophies helps
drive so much of contemporary debates.
At a surface level, it
seems some commentators see a landscape in which the left prefers a
bigger government and the right prefers a smaller one. This is overly
simplistic, of course, and it also happens to be wrong -- for most
liberals, the size of government isn't especially important at all. What
matters are progressive policy goals -- whether those goals are reached
through more or less government intervention is irrelevant.
As
I've argued many times, for the left, political objectives relate to
policy ends. We want to expand access to quality health care. We want to
make investments to create jobs. We want to lower carbon emissions to
combat global warming. We want to see the civil rights and civil
liberties of Americans to protected. We want to reform the lending
process for student loans so more young people can afford to go to
college. There are competing ways to get to where progressives want to
go, but the focus is on the policy achievement.
And with that in
mind, the left invests most of its energy in pushing for policies that
would lead to the desired results. Would an energy policy lead to fewer
emissions? If yes, we want more of that. Would an economic policy lower
unemployment and produce broad prosperity? If yes, sign us up.
For the right, it's backwards -- the ideological goal
is the achievement. Remember
this Jon Chait piece from 2005?
Liberals only support larger government if they have some reason to
believe that it will lead to material improvement in people's lives.
Conservatives also want material improvement in people's lives, of
course, but proving that their policies can produce such an outcome is a
luxury, not a necessity.
The contrast between economic liberalism and economic conservatism,
then, ultimately lies not only in different values or preferences but in
different epistemologies. Liberalism is a more deeply pragmatic
governing philosophy -- more open to change, more receptive to
empiricism, and ultimately better at producing policies that improve the
human condition -- than conservatism.... [I]f you have no particular a
priori preference about the size of government and care only about
tangible outcomes, then liberalism's aversion to dogma makes it superior
as a practical governing philosophy.
Conservatives tend to prefer a different approach that
decreases the role of government, not to achieve specific ends, but
because decreasing the role of government
is the specific end.
This,
of course, affects nearly every debate in Washington. When it comes to
job creation, for example, the task for Democrats is pretty
straightforward: let's do more of what's been the most effective, and
less of what's been the least effective. Again, it's about pragmatism
and results based on evidence.
For Republicans, it doesn't work
quite that way -- they have ideological ideals that outweigh evidence.
GOP leaders could be shown incontrovertible proof that the most
effective methods of creating jobs and improving the economy are aid to
states, infrastructure investment, unemployment insurance, and food
stamps, and they'd
still refuse. Why? Because their ideology dictates the response.
The
left starts with a policy goal (more people with access to medical
care, more students with access to college, less pollution, more jobs,
less financial market instability) and crafts proposals to try to
complete the task. The right starts with an ideological goal (smaller
government, more privatization, more deregulation) and works backwards.
For
Barro, if Republicans "figured out" that their mistaken policy
assumptions were, in fact, mistaken policy assumptions, they'd change
direction. I wish that were true, but all available evidence points in
the exact opposite direction.
