We
Need Privacy From the Government

In Monday’s
Wall Street Journal, L. Gordon Crovitz had an op ed, "Privacy?
We Got Over It." The article is amazing not for what it
says, but for what it omits. That someone could discuss privacy
concerns with virtually no reference to the danger of government
abuse is astounding, and shows that the writer doesn’t really
understand the issues at stake.
Crovitz’s main
point is probably true. He argues that even though people wail about
wanting privacy, they give information to businesses all the time:
We seem to
be following the advice of Scott McNealy, chairman of Sun Microsystems,
who in 1999 said, "You have zero privacy anyway. Get over
it." And the observation by Oracle CEO Larry Ellison: "The
privacy you're concerned about is largely an illusion. All you
have to give up is your illusions, not any of your privacy."
These comments
could be dismissed as technology executives trying to minimize
complaints about technology. But whatever we say about how much
we value privacy, a close look at our actual behavior suggests
we have gotten over it. A recent study by AOL of privacy in Britain
found that 84% of people said they would not disclose details
about their income online, but in fact 89% of them willingly did.
Amazon closely
records our taste in books, Gmail scans our emails to deliver
relevant ads, and electronic tolls track where we drive. Profiles
on MySpace and Facebook are accessible, forever.
Because of
these trends, Crovitz concludes: "We’re in the early stages
of adapting to more digital and visible lives, with privacy expectations
better defined by what we do than by what we say."
What Crovitz
doesn’t discuss is that there is a tremendous difference between
private businesses knowing selected bits of your personal habits,
versus a government agent having access to all of your personal
information. In a related context, Friedrich Hayek pointed out in
The Road to Serfdom that it makes the difference between
tyranny and liberty when central planners "merely" accumulate
in one group of bureaucrats all of the power that had previously
been dispersed among thousands of CEOs and other decision-makers
in the private sector.
Let me spell
this point out to make sure it sticks. Even in a completely free
society where everyone respected private property rights, it would
still be the case that your doctor would know what medications you
were taking, your ob-gyn (if you are a woman) would know whether
you had had an abortion, your bank teller would have a pretty good
idea of how much money you made (especially if you ran your own
business and deposited written checks from your customers), and
the teenager at Blockbuster would know if you rented naughty movies.
The reason
consumers would tolerate these "invasions" of privacy
is that the goods and services provided, would be much cheaper if
the providers didn’t have to adopt costly screening measures. For
example, it would certainly be possible for Blockbuster to set up
its stores and checkout procedures, so that the kids working the
cash register didn’t actually see which movies each customer rented.
For example, the physical DVDs or cassettes could be bar-coded with
no other identification on them. The customers would use a key to
go find their desired title. So unless Rain Man were on duty, nobody
would know if you rented Sister Act 2 every week. (Please
tell me you don’t.)
Even with something
as intimate as medical examinations, strictly speaking it would
be possible to make them much more secure than they currently are.
Yet consumers currently don’t insist on such extreme safeguards
– and presumably in a free society they wouldn’t either – because
they prefer the convenience, lower prices, and higher quality (in
other respects) of the goods and services when they are provided
with a lower threshold of privacy. Just as consumers could have
safer cars if they were willing to pay more, so too could consumers
have "safer" (from a privacy viewpoint) movie rentals
and medical examinations if they were willing to pay more and suffer
other offsetting features.
Ultimately,
in a free market competition would ensure that customers’ privacy
was protected as much as possible, consistent with other desirable
product features. In this sense we can say the market provides the
"optimal" or "efficient" amount of privacy.
If a bank had poor safeguards and its clients’ personal information
repeatedly were stolen by hackers, it would eventually go out of
business. Third-party agencies could provide consumers with ratings
on privacy issues for various businesses.
In contrast,
nobody gets to fire the FBI if they think its warrantless searches
and wiretaps – not to mention all the tax dollars it receives –
are too high a price to pay for the "services" it provides
in, say, finding
anthrax killer(s).
In closing,
let me deal with a good example of why I personally don’t worry
about protecting my privacy from businesses per se, except insofar
as the government can lean on them and assemble a portfolio of your
entire life. I have an uncle-in-law (if that’s a real term) who
is a great libertarian guy, a real gold bug and gun nut. He’s also
a wise aleck – he carries around one of those counterfeit-detecting
pens, and whenever a cashier checks to see if his $100 bill is phony,
he does the same in her face with the $20 bills she gives as change.
Anyway, one
of this guy’s worries is that at some point, grocery stores will
use your "shopper’s club" ID cards (on your keychain or
whatever) to tailor the prices based on the customer who is walking
by the shelf. So the price of bread for me will be different from
what you see on the (electronic) label on the shelf, because our
purchasing histories are different.
I admit that
at first that sounds Orwellian, but what’s the big deal? Right now
grocery stores charge different prices based on which shoppers are
cheapskates who clip coupons. The whole point of personalized shopper
cards is so that the stores (and other marketing groups to whom
they presumably sell the data) can learn more about consumer behavior.
Without those cards, stores would be able to tell how many more
hot dogs they sell when ketchup is on sale, but they wouldn’t be
able to tell how many people who respond to a ketchup sale also
responded to the Rice Krispies sale three months earlier.
Yes, in a sense
it’s true that if the store knows "all about you," and
had the technology to do so, it could adjust the prices you see
as you walk its aisles, in order to extract as much profit out of
you as possible. But so what? That’s what all stores do right now,
except it’s not tailored to you specifically. That is, they set
their prices with the goal of making as much profit as possible,
based on their experience with shoppers and their expectations of
how many units they will sell at various prices.
So
long as there is competition, "price discrimination" –
charging different prices based on the customer – actually promotes
efficiency. For example, suppose that after installing the new technology,
every grocery store sees its profits go up 3 percent. Even so, at
this point every sale would have been voluntary; shoppers would
still value their groceries more than the cash they surrendered
for them. But beyond that, the higher profits in the grocery industry
would attract more entrants, and/or existing stores would try to
attract more business by either lowering prices across the board,
building bigger parking lots, hiring more employees to answer questions,
etc. The ability to charge individualized prices would be beneficial
to consumers, just as they benefit from bulk discounts, frequent
flier programs, and other non-uniform pricing strategies.
The free market
has mechanisms to ensure the optimal amount of privacy is provided,
consistent with the tradeoffs between other objectives. The real
privacy danger comes not from business, but from government.
