I think that in a year I may retire. I cannot take my money with me when I die and I wish to enjoy it with my family while I live. I should prefer living in Germany to any other country though I am an American and am loyal to my country.
Like any business the oil industry runs on the basic premise of supply and demand. The more supply - the lower the price. The higher the demand - the higher price. In other words the more people who can buy oil the higher the price of oil.
