People face trade-offs because to get one issue that they like, they usually need to give up something else that they like. The cost of something happens to be what you surrender to obtain it, not just regarding monetary costs but every opportunity costs.

Rates rise if the government styles too much money because more money in circulation reduces the value of money, causing inflation.
