"Show people tend to treat their finances like their dentistry. They assume the man handling it knows what he is doing"

In this quote, Dick Cavett is making a contrast between how people approach their financial resources and how they approach their dental health. He recommends that lots of people tend to rely on the professionals in charge of their financial resources, similar to they trust their dental experts to look after their teeth. This blind trust can be dangerous, as it presumes that the person in charge is well-informed and competent. However, similar to with dentistry, it is important for people to educate themselves and be actively involved in managing their finances. Blindly relying on someone else to manage your financial resources can result in negative repercussions, similar to neglecting your dental health can lead to severe concerns.
