"Mexico, one of the largest suppliers of oil to the United States, has a big problem: Its production of crude is falling fast...
But industry analysts feel that unless international companies are given ownership stakes in the oil fields, investment will remain low and production will continue to decline.
There's also been recent talk of broader industry liberalization, but it faces strong opposition from the country's unionized oil workers, government agencies that rely on PEMEX proceeds and Mexican consumers, who benefit from gasoline subsidies."
As energy quality falls and its scarcity rises whoever owns what oil is left will be a king. And those who want it are either potential customers or enemies... the difference will depend on who has more firepower.
