Opec and oil prices

Opec says there is nothing they can do about the gas prices and they are correct. Has anyone besides me noticed that oil companies are buying/selling themselves down to a precious few ccompanies?
No matter what name you see on the local gas station, they are all part of one of the few big boys.
The big boys want to drill in Alaska........so.......I smell 'checks' flying around Wasington at record speed. And we have to pay for those checks.
Sounds like a 'capitalist economy' to me.
