This graph tells the story; you can barely see the American oil companies as minor players on the right side of the chart.
The irony is that it doesn't have to be that way. The United States--unlike, say, France--actually has vast petroleum reserves. It would be possible for American oil companies to develop those reserves, play a far bigger role in international markets,
This would be infinitely preferable to shipping endless billions of dollars to Saudi Arabia, Russia and Venezuela.
So, why doesn't it happen? Because the Democratic Party--aided, sadly, by a handful of Republicans--deliberately keeps gas prices high and our domestic oil companies small by putting most of our reserves off limits to development. China is now drilling in the Caribbean, but our own companies are barred by law from developing large oil fields off the coasts of Florida and California.
In short, all Americans are paying a terrible price for the Democratic Party's perverse energy policies.
