Exxon and Mobil were allowed to merge by the Re;publican congress and white house into what it is today. They were originally all part of Standard Oil when the Rockefellers had it until the Sherman antitrust act was used to break them up. Exxon/Mobil is now making more money than anybody else ever has and driven the price way up. However, we can't blame it all on them. If we didn't pay it, they couldn't charge it.
