I'm not completely keen on how gas prices coming down hurts everyone.
Gas prices are directly tied to the price per barrel of oil. The energy industry in America added 100K jobs in the last two years and most of those jobs will disappear with oil being sub $50 a barrel. Most people think gas (gasoline) is tied to exploration and production companies and that is not the case. Refineries buy crude and other petroleum products from the E&P companies. The refineries and the companies that own/operate them are the ones that control the price at the pump. When crude prices are down, they can obviously produce gasoline cheaper, hence the drop at the pump. When the price at the pump drops, it means crude prices are dropping and when crude price drop, production slows. When production slows, there is less need for employees whether it be within E&P companies, oil field service companies, or even companies like US Steel who produces a large percentage of the drill pipe in America. There is a trickle down effect from slowed production. Caldwell, Ohio had a grand total of 1 hotel 3 years ago. In the past 3 years, they have built and opened 1, with 2 more being built as we speak. All to service the oil field. Guess what happens to those hotels when E&P companies pull out of Noble County due to low prices? Those hotels will sit empty and eventually close, eliminating jobs. From rig hands, to welders, to equipment operators, to construction crews, people are going to lose their jobs in mass over the next few months.
So really its quite simple. Cheap gasoline means less jobs.
