Recently I've heard talk on news programs of $4 a gallon

Some economists say increase federal tax to bring gas up to $8 per gallon, ala Europe
prices and taxes. Wow, talk about a major, if not impossible, lifestyle change for Americans (walking to work, school, stores, etc., use local public
transportation and a national train system, return to smaller cars and trucks, etc.)!
Here is what I'm wondering about. For about a year I've noticed new oil wells being erected and working along with old, inactive ones pumping again,
along a stretch of a California highway in Kern County. If there is a refinery problem, why is more oil being pumped? Is it not being refined? If not,
where is it going?
During the years of "oil shortages", the above older oil wells never were working. Now they can't pump fast enough. Is it like my telling my
children I didn't have money to give them, when in reality I had it but didn't WANT to give them any money at times?
