"Printing money" doth not cause inflation. Most money is virtual (checking accounts, etc.) so the amount of currency being printed and minted is a side-issue, really, and it has been for several hundred years. This may seem obvious to the writer, but as a retired high school teacher, I know that a lot of people take things in an over-literal way. Also: it does not "cost more to borrow money" when interest rates go up; the costs of borrowing (closing fees, etc.) remain about the same. It's the paying it back that costs more.
