Just after the USA elections started, the oil prices have gone up. It costs nearly $4 a gallon in the USA at the moment, 30 years ago, it would only cost $1 a gallon 1.Will oil prices EVER go down again, and if so, by how much? 2.How much do you think oil will cost after 40 years or so? These two questions have been bothering me and a lot of people for a very long time, I'd like to hear your opinions
