Ooooh, I was looking forward to a topic like this in the future, it is
a lot of fun. I am going to answer the questions out of order, but oh
well.
The answer to the second question on prices is simple. Oil is a
natural resource that is drilled for and pumped out of the earth.
Crude Oil while it is pumped out of the ground is unrefined and almost
wholly useless. You have to first refine it and separate some of its
components out, which can get you motor oil, regular gasoline, diesel
fuel, kerosene, coke (not the smoking kind, but the kind used to make
steel), tar, and more. So the price of oil really just increases the
input costs of gasoline, making gasoline more expensive rather than it
working the other way around.
As for question number 4, some countries pay more than we do and
others pay less.
A good list of some of the prices that existed on May 1, 2008 (from
the Associates for International Research, Inc. - AIRInc):

The data shows that Norway pays the most at $8.73/gallon, and
Venezuela pays the least at $0.12/gallon. The nations that pay the
least all make a significant profit from oil drilling industries in
their nations, and since it is a predominant industry for them, they
can force their mostly government owned companies to charge their
citizens less for oil than they do the rest of the world.
Question 5 is important and I will give it an answer in contrast to
number 3, to try and reveal my perspective on the differences in the
situations. In the 70s, the primary source of oil was Arab nations,
which while they still control the lion's share, they are responsible
for a significantly smaller portion of the supply today than in the
70s. In the 70s, the oil producing nations, under the coalition of
the organization of petroleum exporting countries (OPEC), which was
made up of Arab nations, refused to send oil to any nation that had
supported Israel. That included the United States, so the supply of
Oil available to the U.S. was reduced, and the prices shot through the
roof. To combat the price rises, the government tried to stop the
rise with price controls, which ended up hurting the economy and the
value of the dollar (yes this is all debatable, but there is good
evidence that those decisions are what did the harm), so when the oil
embargo was rescinded a year later, the dollar was much weaker and the
price could not fall because the purchasing power of the dollar had
been hurt so bad.
Today there is a difference in the reason for the pricing changes,
well two actually. Supply has been hurt a little by the Iraq war, and
we all expected costs to go up because of that, but that is not the
biggest cause of the price increases. The biggest reason for the
increases is that China now uses 6 times the amount of oil it used 10
years ago. The shift is massive, and since China has been using the
increase in oil usage to industrialize, they do not appear to be
needed less oil in the near future, so the prices are not likely to go
down any time soon without either (1) us dropping our gas tax, or (2)
us drilling for and producing more oil.
A recent congressional report issued stated that only 40% of the oil
permits that have been issued are being used (that is to explain why
they do not want to open up ANWR). We do not know the value of the
areas where the permits are not being used, but we know that there is
still untapped oil in the U.S.
So I guess what I have been saying is that Supply and Demand have done
most of the work, but our government in Iraq has reduced the supply of
oil while an exterior force has been increasing demand making prices
higher. Now OPEC does not have the same power they did in the 70s and
an attempt to hurt the U.S. in this manner now would not be as
successful, since the nations competing with them are willing to
undercut their prices to get ahead, removing most of their clout.
Also, since the U.S. is still the biggest user of oil, by refusing to
sell to us, they would be hurting their own profits, and since we are
fickle to prices, we are not overly picky about who we buy from.
Now as to what control we have over the Oil Market, we have a lot, we
can tax, and drill, and give any kind of federal funding to shale oil
research (it is all private now, and much of the land on which shale
oil is found is protected by the government), and more. The reason
for not doing this stuff is largely political. The ELF (Earth
Liberation Front), argues for raising the gas tax in order to force
research on renewable energy so that we can stop people from using
gasoline - other organizations that are significantly less extreme
agree with this as well, but state it in round-about terms. They want
to make it harder to drive and to convince people to drive less so
that our carbon footprint is reduced, and they are shrewd enough to
know that economics is a good way to accomplish that. There have been
those fighting against it, and those fighting for it, and so gas taxes
rise and fall as do the number of permits allocated to drilling based
on the political make-up of the government.
I know this is a long answer and doesn't nearly get into the details
of it, but these gas prices are probably here to stay, and there is
not much that our government can do about it.
