Seems that no one remembers that before the mid 70’s oil embargo (about 36 years ago) there were GAS PRICE WARS everywhere.
Gas was .28 to .30 CENTS a gallon. The oil companies quit using our oil for the “light, sweet” crude of the middle east, which, IMHO, allowed the allowed the Arabs not only to embargo and rise prices, but to cause American money to be sent overseas.
Our next big SNAFU was NAFTA. Another government mistake that still sticks in my craw.
Try a search on Nixon and the gold standard. A lot of the price appreciation is dollar inflation.
