I'm not saying I agree with everything he says, but he makes some interesting points. In his recent annual letter to his shareholders, Buffett said the following about gold (see pg 18-19):

The second major category of investments involves assets that will never produce anything, but that are
purchased in the buyer’s hope that someone else – who also knows that the assets will be forever
unproductive – will pay more for them in the future. Tulips, of all things, briefly became a favorite of
such buyers in the 17th century.

This type of investment requires an expanding pool of buyers, who, in turn, are enticed because they
believe the buying pool will expand still further. Owners are not inspired by what the asset itself can
produce – it will remain lifeless forever – but rather by the belief that others will desire it even more
avidly in the future.

The major asset in this category is gold, currently a huge favorite of investors who fear almost all other
assets, especially paper money (of whose value, as noted, they are right to be fearful). Gold, however,
has two significant shortcomings, being neither of much use nor procreative. True, gold has some
industrial and decorative utility, but the demand for these purposes is both limited and incapable of
soaking up new production. Meanwhile, if you own one ounce of gold for an eternity, you will still
own one ounce at its end.

What motivates most gold purchasers is their belief that the ranks of the fearful will grow. During the
past decade that belief has proved correct. Beyond that, the rising price has on its own generated
additional buying enthusiasm, attracting purchasers who see the rise as validating an investment thesis.
As “bandwagon” investors join any party, they create their own truth – for a while.

Over the past 15 years, both Internet stocks and houses have demonstrated the extraordinary excesses
that can be created by combining an initially sensible thesis with well-publicized rising prices. In these
bubbles, an army of originally skeptical investors succumbed to the “proof” delivered by the market,
and the pool of buyers – for a time – expanded sufficiently to keep the bandwagon rolling. But bubbles
blown large enough inevitably pop. And then the old proverb is confirmed once again: “What the wise
man does in the beginning, the fool does in the end.”

Today the world’s gold stock is about 170,000 metric tons. If all of this gold were melded together, it
would form a cube of about 68 feet per side. (Picture it fitting comfortably within a baseball infield.) At
$1,750 per ounce – gold’s price as I write this – its value would be $9.6 trillion. Call this cube pile A.
Let’s now create a pile B costing an equal amount. For that, we could buy all U.S. cropland (400
million acres with output of about $200 billion annually), plus 16 Exxon Mobils (the world’s most
profitable company, one earning more than $40 billion annually). After these purchases, we would
have about $1 trillion left over for walking-around money (no sense feeling strapped after this buying
binge). Can you imagine an investor with $9.6 trillion selecting pile A over pile B?

Beyond the staggering valuation given the existing stock of gold, current prices make today’s annual
production of gold command about $160 billion. Buyers – whether jewelry and industrial users,
frightened individuals, or speculators – must continually absorb this additional supply to merely
maintain an equilibrium at present prices.

A century from now the 400 million acres of farmland will have produced staggering amounts of corn,
wheat, cotton, and other crops – and will continue to produce that valuable bounty, whatever the
currency may be. Exxon Mobil will probably have delivered trillions of dollars in dividends to its
owners and will also hold assets worth many more trillions (and, remember, you get 16 Exxons). The
170,000 tons of gold will be unchanged in size and still incapable of producing anything. You can
fondle the cube, but it will not respond.

Admittedly, when people a century from now are fearful, it’s likely many will still rush to gold. I’m
confident, however, that the $9.6 trillion current valuation of pile A will compound over the century at
a rate far inferior to that achieved by pile B.

Our first two categories enjoy maximum popularity at peaks of fear: Terror over economic collapse
drives individuals to currency-based assets, most particularly U.S. obligations, and fear of currency
collapse fosters movement to sterile assets such as gold. We heard “cash is king” in late 2008, just
when cash should have been deployed rather than held. Similarly, we heard “cash is trash” in the early
1980s just when fixed-dollar investments were at their most attractive level in memory. On those
occasions, investors who required a supportive crowd paid dearly for that comfort.

My own preference – and you knew this was coming – is our third category: investment in productive
assets, whether businesses, farms, or real estate. Ideally, these assets should have the ability in
inflationary times to deliver output that will retain its purchasing-power value while requiring a
minimum of new capital investment. Farms, real estate, and many businesses such as Coca-Cola, IBM
and our own See’s Candy meet that double-barreled test. Certain other companies – think of our
regulated utilities, for example – fail it because inflation places heavy capital requirements on them. To
earn more, their owners must invest more. Even so, these investments will remain superior to
nonproductive or currency-based assets.

Whether the currency a century from now is based on gold, seashells, shark teeth, or a piece of paper
(as today), people will be willing to exchange a couple of minutes of their daily labor for a Coca-Cola
or some See’s peanut brittle. In the future the U.S. population will move more goods, consume more
food, and require more living space than it does now. People will forever exchange what they produce
for what others produce.

Our country’s businesses will continue to efficiently deliver goods and services wanted by our citizens.
Metaphorically, these commercial “cows” will live for centuries and give ever greater quantities of “milk”
to boot. Their value will be determined not by the medium of exchange but rather by their capacity to
deliver milk. Proceeds from the sale of the milk will compound for the owners of the cows, just as they
did during the 20th century when the Dow increased from 66 to 11,497 (and paid loads of dividends as
well). Berkshire’s goal will be to increase its ownership of first-class businesses. Our first choice will be
to own them in their entirety – but we will also be owners by way of holding sizable amounts of
marketable stocks. I believe that over any extended period of time this category of investing will prove to
be the runaway winner among the three we’ve examined. More important, it will be by far the safest.
