Purpose of having good credit when you are well-off?
Credit in general having no significant change between an income level or net worth is due to the economic reciprocity principle inherent in many societies. Although some areas of credit may be more admirable to those who aren't as well-off, such as car loans, the overall understanding of credit is a trust agreement between someone getting something (e.g., credit card user) and someone giving something (e.g., bank or company). Credit doesn't have to mean just money -- it can be anything of value, including tangible materials, services, etc. The fact is that a credit is a common element in most economical systems, and as such its use is not really variable between income levels/etc. Sure, there is variance in things like credit line amounts and rewards, but the overall gist is the same for everyone -- borrowing, paying back, benefits, etc. All of these exchanges form the same understanding we all know and follow. Credit brings along with it trust -- the form represented in a score. While not everyone may depend entirely on credit, and no one should use credit as a means of getting by entirely (money), everyone can understand and reap the benefits of a system whether they make 10K a year of 10M a year. This is the general idea behind credit in the broadest sense possible. Besides, just because one has or makes more money doesn't mean they don't prefer to get good deals. Nobody should like being taken advantage of, and if credit can help, anyone can establish trust.
