The problem is that there are a lot more "successful people" with a degree nowadays, but not that much more demand. Thus the value of nearly all degrees is lower now than decades ago. Only ones with difficult entry (like medicine) really hold their value. Even CS degree is fairly useless without hobby projects or working experience.

Many university programs exist simply to make money, or in European publicly funded institutions because of arbitrary government targets for raising education level in general population. Nothing to do with actual demand or applicable skills in workforce.
