The problem will always be the media and its catering to the public and money.
Schumann wasn't heard of and worse, wasn't liked. Other composers of less quality were more famous. Even though a few knew of his genius, he just couldn't become popular.
Today, there are worthwhile artists out there. But they are hard to uncover. The general public has horrible taste in music, But what the general public wants, they get. Always will, always has. To say music has stopped being worthwhile is ignorant. There is just an ever increasing pile of crap and it becomes harder to sift through every day.
The only possible way classical is superior is because a LARGER percentage of it doesn't sacrifice it's own self proclaimed art for money, fame and shallow purposes. It still does, but not as often.
Most other forms nowadays are more interested in money than artistic purposes. Jazz is an exception. Rock, Pop, Rap, R&B, Techno are almost all about an image or clubbing or money. A Small percentage of them are not, but most are.
This is the only difference. The reason classical earns such respect is because of it constant pursuit of the new and the impossible and the divine.
Again, however, to say classical is superior music is, for the most part, subjective.
