The concept of credit scores has a reason to exist, it's just our implementation is broke a million times over. There's nothing wrong with a business loaning you money having the knowledge aforehand that you don't pay your obligations on time.
If by "under the thumb of" you mean "using less than 30% of available credit and carrying some kind of balance". There's no need to apply melodrama to a simple matter of statistics to answer the question of whether someone can use credit responsibly.
