People need compensation for their effort, its one thing to help someone out that doesn't require skill or time , however, when you need someone that is trained , or thier help requires them to put in time, like medical or farming, there has to be equal compensation, and since you are not a DR or a Farmer, giving someone money as payment is how you give back to them . Money is a tool that is used to compensate someone for a skill that you don't have or time that they used to help you. Money is not good or evil, it is a means to an end.
