As we've all noticed, gas prices have been going up lately (again).
An article at the personal finance site Wise Bread mentions some ways that gas prices could be brought back down again (essentially, reverse the direction of speculation, since prices are speculation-driven), as if the best thing for us all would be if gas prices were to drop.
I actually think higher oil/gas prices are a good thing.
Why would I say that?? It's because our country's energy and transportation policies and expectations are largely based on the assumption of cheap energy for the foreseeable future. That assumption in turn drives our foreign policy - leading us to questionable "allies" and increased military expenditures that often don't demonstrate direct benefits for the U.S. - not just wars, but protecting certain shipping lanes, for example.
Higher gas prices lead to conversations about energy policy that we as a nation need to have. It may hurt in the short term, but hopefully it helps us figure out some longer-term solutions.
