One of the bigger issues is that a single internal metric, used to assess risk by lenders, has been turned into and promoted as a pseudo social-credit score.
Worse, many don't know what it encompasses, how it is used, and resist gaining a better understanding, while harboring an unhealthy obsession over it.
Then there are those who proudly proclaim to be debt-free, which is a admirable goal, if not practical for a lot of folks, then expect to be rewarded in some fashion for not demonstrating the very thing that the metric is designed to measure -- the responsible use of credit.
Trying sitting down in an job interview with no relevant, or recent experience, or blank employment history, and then explaining to the interviewer why they should hire you, since you haven't demonstrated that you'll be able to do the job, and see how that goes.
Then imagine it's a lender, not your potential boss expecting the same when you attempt to borrow money. Neither is just going to blindly accept your word, or give you credit for being the good employee you say you have been, without showing it. And both will be considering more than the words on your CV to make their assessment.
It's a game, no doubt, but their game, and their rules. The lucky can choose not to play, but for those who must be a player, if behooves one to understand the rules of the game, and how it is played.
