As I said earlier, high profits, or any profit above opportunity cost, are a measure of market inefficiency. Basically, any profit above that which is required to entice investors is inefficient. This has some different ramifications with publicly held companies as many people speculate in stock, not invest.
Anyway, let's assume for a second that a company like Exxon Mobile which has a 9% profit margin could still entice people to buy the stock, basically buy opportunity costs, at 3% profit margin. Theoretically, they could capture more of the market by reducing prices and thus still maintain or increase aggregate profit while reducing margins, but this is largely a price fixed market due to inelastic supply. Anyway, that 6% difference is inefficiency.
Further, let us assume that this type of inefficiency is found throughout the market and accounts for 6 cents of every gallon of gasoline you purchase (a relatively small number). If the average person has a car that gets 20 MPG and drives 40 miles everyday to and from work then that person pays 12 cents a weekday and maybe 6 cents a weekend for errands and such. That comes out to be approximately $137.28/yr while not including road trips, etc.
Now let's assume I'm an investor. The above market inefficiency has increased profits and thus increased (hopefully) dividend paid. I go to Exxon Mobil and see that the dividend paid is (forward annual dividend yield) is 2.5%. That means at present stock prices, I have to invest about 5k just to break even this year in terms of the amount I've already paid for inefficiency.
But, of course, most Americans likely don't have 5k in cash to invest in the market. They still have to pay for the inefficiency, but they are getting no returns. Even if they bought $100 of Exxon Mobil a month, it would take over 4 years to get to the point where they were breaking even. And they paid for market inefficiency all of those four years.
Not to mention that if everyone did as you suggested, the demand for oil stocks would be huge, thereby driving the value of the stock up, thereby killing yields. Of course, along the way of rising prices, more and more people would be excluded due to price issues. And, of course, speculators would try to hop on for the free ride. It basically means that established capital has a huge advantage as they can out bid any newcomers and lock them out of the market.
As more people invest, the more one needs to invest to recover those inefficiencies (from an investor's standpoint). And the more stock one has, the more I profit from those inefficiencies even though I may not use more gas and thus pay more for those inefficiencies as well.
It becomes a real problem when you consider
this. On aggregate, only 49.7% of people in 2004 held retirement accounts and only 20.7% held stocks. Of course, these numbers rise steadily as family income increases. In other words, poorer people are not reaping the benefits of these inefficiencies but are still paying for them by buying gas. They can't just all simply enter the market because it would drive prices up and dividend yields down either making the stocks unaffordable or crushing the yields to the point where they could never expect to repay the inefficiency they pay everyday.
Market inefficiency is simply a redistribution of wealth from people that don't have capital to those that do. Now, with some commodities one might say this is ok. If there is price fixing behavior occurring with TVs for instance, the redistribution is still occurring but people really don't need to buy TVs. They don't have to give their money to those with capital. Oil and energy is a different story. Most people do have to buy gasoline to get to work. And the poorer you are, the greater the burden these inefficiencies become on you. Then you can see why high profits in commodities that are necessities can be a problem, even for people with some capital.
Of course, in a perfect market there would be no inefficiency. Then again, a perfect market requires conditions which never exist in the real world.
