Wouldn’t it be
cool if you could throw a bag full of stuff into the air and it would stay
there, suspended in the air. It would be cool and it could probably help a lot
of people. But science says “what goes up must come down.” We don’t argue with
science and while man-made elevators and forklifts have been invented to lift
things for us – one still can’t throw a sock full of rocks into the air and
hope it will stay up there.
Even if we
had a lobby group and a new political party decrying the mean and arbitrary
nature of the Law of Gravity, that wouldn’t change matters. We are stuck with
the science. You shake your head and wonder how many JDs I have thrown into the
air tonight. But the truth is that we are witnessing these days the tragic
retraction of science and reason in our lives. Perhaps because economic
well being is tougher to achieve now we want to reject a lot of complicated talk about
economic issues. We just want action. We want results. We don’t want "on the one
hand this and on the other hand that".
And so we
have political candidates who will tell us anything – anything that makes us
feel better. Trump will build a wall. Cruz will bomb the bad guys. Hillary will
make women taller. Bernie will give us free education. We will raise the minimum
wage and people will live better.
There is
nothing wrong with wanting more equality and safety but these politicians focus
their energy on ideology and goals without taking the time to explain exactly
how and why their actual policies might bring about these results without throwing the baby out with the dirty bath water.. Using ideology and wishful statements, of course, worsens
the country directly because it often pits us against each other. The last I
heard this was a country with shared values and interests. We depend on each
other. It makes no sense to think that
anything will be resolved by making us even more separate and resentful.
The solution
to all this is as it always has been -- science. Think about it. Maybe you were
not the brightest science student in school. But the evidence that we trust
science is everywhere. Biotech drugs are finding new ways to cure cancer. We
can hope for a cancer cure, but I like the odds of Lilly's biologists working on this
problem. Or take Moore’s Law which explains why you can get more and more power
out of smaller and smaller computer chips. Again, hope has little to do with
all this power and convenience we obtain.
So if
biology, chemistry, physics and the other sciences are so helpful, why are we
so willing to reject or ignore the learning from economics? We often rely on
economic laws. Many businesses know that the quantity they sell will depend on,
among other things, the incomes of consumers and the prices of their
goods. Business firms also understand
that a lack of resources makes it harder and more costly to produce goods and
services. Economics is a soft science in the sense that the predictions might
not always be right on the money, but predictions are based on
generally accepted basics and logic.
A good
example of all this is the recent legislation in California (and other places)
raising the minimum wage to $15 an hour. Asked why this legislation is
necessary, the promoters explained that it is unfair for people in California
to make less than $15 per hour. The general answer is about fairness and not
about science. Science be damned – it sounds very desirable to think that a
government can raise a magic wand and make people’s lives better.
Economic
science does not care who you are. In physics the focus is on atoms or subatomic
particles. In economics we focus on people. But in neither case are we driven by fairness. What we care about is doing what is best for the community or
the system. Consider some of these economic facts. First, the wage of a person
is determined by the impersonal forces of supply and demand. We have seen it
many times. When nurses are scarce, the wages of nurses rise. Is this fair to
cab drivers? When people switch from coal to natural gas coal miners are needed less and their wages fall.
None of this is about fairness. It is about using economic science to explain
why wages and prices vary across people and places and over time. Prices and wages are signals -- precious signals that allocate goods and services from one place to another as needed. We don't need government czars telling every company what to produce. Markets perform these functions day after day.
Second,
raising the minimum wage begs the question – to what amount? If raising it to
$15 per hour improves fairness, why not raise it to $20 per hour? The nice
thing about the market is that wages move to resolve imbalances. But
when your local Mayor is grubbing for votes, she talks about things like a
living wage or some such thing. Apparently a person cannot live unless every
member of his family is making the government determined living wage. And what does it take to live, anyway? I hope they include JD in that bundle of goods.
Third, let’s
keep in mind the fairness involved with everyone. Suppose there are people
making $15 per hour today. When you raise some people to $15 then you have to
raise those people to what? $20? And the people who were making $20 must be raised to
$25? And so on. So now you have the government determining everyone's wage. Can we really do that? Unless of course you want everyone to make $15 per hour. Is that fair?
Fourth, a
part of economic science is the theory of the firm. If firms have to pay
workers more, they have three choices – take lower profits, reduce the number
of employees hired, or raise prices. If firms raise prices of their goods and services the minimum wage
worker has not in fact been helped. If the prices of the goods you buy go up by
a similar amount as your wages, then your wage still buys the same amount. Of
course if owners or other workers are harmed, then you have clearly harmed
someone in the name of fairness for someone else. What happens when those people react to those harms? Will that be good for the minimum wage workers?
There is
plenty more to say but that should suffice for today. The minimum wage is not
about fairness. It is about helping or pleasing some voters at the expense of other voters.
The minimum wage distorts science in the same way that using leaches cures
modern diseases. The minimum wage is not proved to be fair or to improve the
lives of workers. Governments cannot tell a worker what he or she is worth. A
worker’s worth reflects education, training, experience, contacts, and an abundance of
luck with respect to supply and demand. If you want to help poor people, it
would be much less destructive to use other methods that more directly address
education, training, contacts, and luck.
