It is really crazy. I guess maybe the problem is keeping the weight
down on bike tires. I just wish I could get the full 3,000 miles or
so out of a rear tire before it suffers catastrophic damage.
Well, it's not just tires, if you want to calculate things in those
ways. $25,000 will get you a roughly mid-range car that weighs maybe
3500 pounds. $800 or so will get you a roughly mid-range bike that
weighs maybe 23 pounds. The car buyer pays about $7 per pound. The
bike buyer pays about $35 per pound.
The economics isn't controlled by cost per mile, cost per pound, or any
other such metric. There's lots of influence exerted by the size of the
production run (stuff made in bulk is almost always cheaper per unit),
the degree of difficulty in the design (bike stuff has to have smaller
safety factors to be able to give competitive performance, so more
careful design and construction are needed), the amount of exotic
materials (e.g. kevlar beads), etc.

Anti-puncture belts have historically been known to introduce losses
which relate also to poor milage, but a pure racing tyre is going to
have a thinner tread anyway. Your best bet is to look for a simple 2-
ply or 2.1/2 ply carcass construction with a single tread compound.
The heightened traction at the sides of the Michelin will cause the
centre to slip more, so worsening the the problem of centre wear.
Michelin also fail to offer a larger size, which is important for a
back wheel. A rider over twelve stone is going to have much trouble
in preventing pinch punctures and as such will be using a small
contact length due to the the extreme high tyre pressure. The result
is increased centre wear. A 23mm wired-on tyre will never be the
match of a tubular. If you insist on using this size in wired-ons as
a back tyre you had better be less than 11 stone.
The Michelin Pro Race is for lightweight racing. Don't expect
anything more from it. If you can afford to use it as an everyday
tyre, that'll keep the Michelin shareholders happy.

Good Luck!
If you had ever worked on a car, you would not wish for bikes to
become more like cars, Good cars have more in common with BSOs than
they do with good bikes.
If you compare the cost/size/mileage of radio control model tires to
bicycle tires, you'll find another price gradient.

Regular old getting around tires are $10 or so. Should last 3K.
Comparing race tires, where the economy of scale bites you in the ass,
is a little silly. My last two sets cost $0, being takeoffs from new
bikes where the owner could't leave well enough alone...
Apples and oranges.
The auto equivalent of a Michelin Pro is $600 each and used
for one race then maybe for one practice the next week.
Basic Michelin City are $24.95 and last through years of
daily use.

The asking price on products usually has quite a range. The full gamut
of market forces are in effect for tires as any other consumer
product. If the question is concerning perceived pricing, you may be
paying full prices that few others are willing to pay. In short, they
ask what they expect the very highest price some will pay, but without
knowing just how many pay that price, all I can say is that if you pay
that much for tires, you look to shop around and survey cyclists for
more ideas. I doubt very many pay more than even $30 per tire, never
mind paying full MSRP on top models.
Some industries and market-niches have lots of discounts compared to
others, the question and answers can seem near endless. There is no
easy answer, but I worry about the assumptions you make in asking.
Let us face it. The exact same car as the Honda NSX (Acura NSX in the
US) would have sold much better if it's price was 50% *higher* and it
had a Ferrari badge. Most exotic cars are bought for showing off, not
for any inherent value.
Just like uncomfortable and inferior Harley-Davidson cruisers outsell
"metric" sport-touring bikes in the US, despite the latter costing less
and out-performing the H-D in all objective ways - it is all about image
and social status.
