It will take some cutting back, but not that much. It isn't like oil is becoming cheap, and OPEC will take steps to insure that doesn't happen. They have gotten used to $80 a barrel and don't want it to go higher or lower. And while there isn't much they can do about it shooting up higher, they can easily keep it from going lower by cutting production.
Chavez is really the only one with a big problem. He has used high oil prices to finance a lot of short term international projects rather then working on the fundamental infrastructure and economic problems of the country.
