What do the descriptions of the people from Capitol in Mockingjay remind you of in our population?

According to the book, the citizens of Capitol are the wealthiest and most powerful people in all Panem. They are described as shallow and materialistic people who care only about their appearance; they undergo numerous surgical procedures to look more beautiful and unique and often dye their hair in different colors or tattoo their bodies with various tattoos. The Capitol is a tyrannical, oppressive, and autocratic society, and its government has total political and economic power over the Districts. I find similarities between the behavior of the citizens of the Capitol and the behavior of today's richest people, a lot of celebrities, politicians, and even some influencers; in our world and culture, we have people who care for meaningless and frivolous things like who is the best dressed, who has the most expensive jewelry, or who has the fastest car, while the majority of the population is struggling to survive and is living from paycheck to paycheck. We also have discrimination and oppression to this very day, and it seems that people only care and "do" something about it only when it benefits them somehow. In fact, it is clear that the social structure of Panem is a critical analysis and commentary of today's modern American society and its clear divide between the rich and the poor.
