They say it could happen, at least in some places in the US. $4 a gallon gasoline may not sound like a lot if you're from another country, but we're not used to it and it's going to hurt.
Although we've kind of got used to the idea of higher and more unstable gasoline prices, we'll be upset by even higher prices. Most - or at least, many - places in the US don't have adequate public transportation, and there is little demand for it.
Why? Because we're so independent. We like having our own transportation so we can go where we want to, when we want to and get home with two minutes to spare if we like. We don't mind paying for mandatory insurance, new tires, oil changes and car washes. Just don't ask us to pay much for gas.
Things get out of whack now and then when it comes to priorities, don't they?
Independence is good when it's not extreme, but extreme is hard to define. I don't have any answers and I'm not suggesting that we go to all public transportation, but maybe... just maybe. Maybe we could step back from the independence microphone long enough to see that sometimes it makes sense to dig in, shoulder the responsibility and give up just a little freedom - not much, just a little.
