It's not that we are "giving the Saudi's dollars", the agreement was for Saudi to trade oil in dollars only regardless of the buyer. All countries trading with them would need dollars. This creates a demand for dollars and has for a short time kept some value in the dollar. Less demand is not good for any one holding dollars as it will soon be worthless. Your purchasing power will be greatly reduce. So your statement is true "be more for everyday Americans" you will need it!
