Why common people support royalty/noble class?

Hi. I understand that not too long ago the stories about Kings, princesses and princes were basically a form of entertainment for common people, like watching a movie. Today this isn't true anymore, so why some/many people from the lower classes seem to adore royalty and noble class, even sometimes getting upset if you say something against them?

I mean, the same concept of a "noble" class splits the human kind in class a and class b humans. How can you love and support something that OPENLY consider you a subhuman at its service?
