Looks like someone just googled and then realised how little he actually knew about the topic of conversation.

An overdraft, arranged or not is entirely different from a loan. For one thing, a loan is charged by arrangement fees and an APR, whereas overdrafts you pay in fees and interest. If you need the difference between APR and interest explained to you, you are probably beyond hope. In the UK credit legislation has the intended effect of making unintentional overdrafts the same as intentional overdrafts, unfortunately there is some way to go.

You are also very unlikely to get an overdraft that is subject to a settlement arrangement.

Do I have to explain why rich people do not take out loans or retail credit, or can I go back to ignoring you again?

So anyway, ignoring Rick, my point is that people should realise the difference between different finance products rather than seeing it all the same process with different names. It isn't, it isn't all mashed together. That way, people can get hands-on with their funds and start to use it as a means to an end, rather than hoarding it and then trying to "beat" the system by just making/earning more. There is more going on here that just some people being more affluent than others.
