And I can find stations in the US that are over $6 a gallon. What we want to look at is the gas prices being seen by a reasonable number of people. We can look at US average, state average, or regional average. But it's getting facetious to start picking out single stations and say, "Look, at State and Jackson I pay $5.05 which means that everyone in Chicago is getting shafted despite the fact that at State and Ohio I could pay $4.89." At that point, the difference in price isn't because of difference in the price of oil, transportation, taxes, wages, or cost of living. It's just purely the premium that can be charged that people will still go there and pay out of personal convenience. The whole point is how far do we allow things to get bent before we dismiss them.
I don't think that saying when gas is $4.51 that it's $5 gas. That's around $6-$7 difference at fill-up. And I don't think we can just sit here and cherry pick to find the prices that we want. Why can't I say that since there is a station that's $4.35 at its highest and thus we can still find gas under $5 that we never hit $5 even if it was the only station in town to be under $5?
The averages take into account the parts of town where prices are less as well as the parts where prices are more ...
In the suburbs of Chicago, gas is usually about 20-40 cents per gallon less than within Chicago city proper (depending upon which county/city you're in. Usually the farther out you get, the cheaper it gets) Then, depending upon which part of the city you're in .... the rates also vary to some degree... (to make up for expensive real estate costs for instance, or to make up for security costs or some other factor.)
If the average was $4.50 in the city of Chicago, then the suburban average was probably about $4.25 or so.... but the rest of the state would have been a bit less.
A good percentage of the gas stations in the city would have been even more (especially in super dense city center "Chicago loop" area where everything costs a lot.)
So, even if gas was $5+ at only 3 or 4 stations, it could have been 3 or 4 of the busiest stations...
When you complain about how high the price of something gets, you don't take an average or median, you take the worst examples of what you've seen in person ...
