excuses for why oil companies don't want to build refineries - funny
Every other year or so, something happens to a refinery and gas prices shoot up. Assuming (falsely) that oil companies would make more money by keeping the supply steady, then they certainly would build refineries (and possibly - just possibly - complaints of how hard it is to do so might be other than silly).
The fact is that oil companies make more money when the supply is tight. Every time there is a refinery fire, they make out like bandits. Remember "supply and demand"?
