Do you think a lot of degrees are completely useless, when it comes to real life?

No, learning different techniques in management helps people to avoid the mistake of implementing ineffective management styles. This will save money, time, and perhaps jobs. Knowing business skills is incredibly useful in real life. Now, will a major in English and film studies or art history be relevant in the daily lives of most individuals? Not likely, but that doesn't mean it is not relevant for anyone at all.
