Not the bankers (poor groups have no role in deciding the rates, do they?), but the bank owners charge customers high rates of interests to amass billions of dollars of profit every year. These banks are ripping and squizzing customers luring them with attractive offers at the beginning and piling charges on various topics after the scapegoat joins the offer. I have not much to do with the banks but my plain suggestion is don't get attracted with lucrative offers to change your mortgage or whatever lender. Stick on to the bank with which you have been banking for long. Banks and building societies are profitting more and more every year. Far more than their investment deserves. The Governments most levy huge tax to control their profits.
