Yes, there are some young rulers spoilt by the wealth and power of their family.
But they need to show that in a different time, people behaves differently. It used to be okay to accept living in poverty, but now, people began flinging off their wealth and comfort through Instagram, so everybody wants to get rich. Religion used to be the guiding principle in everything, even in morale. Religion used to represent the more civilized and advanced thoughts in civilization. Then, butlers, like Bruce Wayne's Alfred are proud about their job despite their meager income, and treated like family. They can have a say in family matters despite not being your relative. Kinda like how Jon Snow or Theon can become "brothers" or how Ser Rodrik can sometimes be "above" Stark boys. Now, during the segregation era, black people are treated worse, but many of the successful ones are 100% gentlemen of class that is rare in 21st century, and still they are discriminated against due to their skin colour. As a minority, I also faced with the slightly similar situation, like "my culture" being suppressed (not allowed to celebrate Lunar New Year, learning Mandarin publicly is banned, etc). But honestly, I felt nothing during my childhood. That is probably why many of the bastards in GoT universe can just accept what they are, as long as they life comfortably.
That was the bygone era, such prevalence can't just exist in today's militant minds. It is as if people wanted to rewrite the history to suit their needs. However, this is just a minor scuff, GoT settings in overall is still beautiful and well done.
On the other hand, strange things from the history like Mozart's fecal fetish, Einstein's playboy behaviour, or how composer during the classical era were "poor but with class" (akin to 70s prog rock lyrics). We never seen these characters in a movie with historical setting, except in some European movies. Why? Too strange to be non-fiction?
