It is interesting that we are so quick to cry "greed" when the fuel prices jump. "Those darn oil companies!"
All they are doing is supplying a commodity we all need.
Lets direct some of aggravation at "big corporate" home builders for flooding markets (CA, NV, FL) with outrageously expensively home (typically built with low cost immigrant labor) and mortgage companies that loan money to anyone despite little evidence that the buyer will be able to pay the loan back.
Greed has caused a near collapse in the loan industry and a collapse of value of the US dollar. $1. 40 buys 1 Euro, the Canadian dollar is now par with the US dollar. Remember this when your company gets bought by an international conglomerate and your boss has to report to his/her bosses in Germany, the UK, India or Dubai.
We, as consumers, have to take control.
For oil, do what you can to reduce demand. Drive slower, combine trips, run that errand on the way home rather that making a special trip.
For other things, we need to read more carefully and ask questions. If the deal seems too good to be true, back away. Read labels, and say "No" when your kid wants that silly little toy in the dollar store or Wally World. If there is no demand for stuff from China, their need for energy will be reduced. Put the money you save in the bank. The US savings rate stinks because we "consume" too much.
Ok, I feel better now, I'll get off my soap box now.
