I'm inclined to think the families who buy into it are hopeless snobs.
Lets see:
Prince Luiz, the Head of the Imperial House, is a 75 years old man who had polio as a child, and still have locomotor problems because of that. He always presiding over Monarchist Meetings, his house, in São Paulo, is always open for Monarchists from all over the country, he gives interviews all the time. His address is availabe on internet, anyone can come to visit him.
Prince Bertrand, the Prince Imperial, is a 72 years old man, who travels the entire country, presiding over lectures about Monarchy. He also engaged with many causes that politicians are afraid to get envolved.
Prince Antônio, the third in the line of succession and Prince Rafael's father, also travels around Brazil, visiting schools, orphanages, hospital and even prisons (politicians here never go to those places). He's now retired, but he used to have two jobs.
Princess Cristina, Prince Antônio's wife, is envolved with charities to help mentally disabled children. She always take part in charity events.
Prince Rafael, the fourth in line to the throne, is now working as engineer for a great company here in Brazil. He also travels with his father and attend meetings, on behalf of the Monarchist Movement.
Princess Amélia, Prince Rafael's older sister, who is fifth in line to the throne, is now living and working in Spain, she's an architect. But, when she's in Brazil, she take part in the Monarchist Movement. And she also helps her mother with charities.
Princess Maria Gabriela, Prince Antônio's youngest child and sixth in line to throne, has recently graduated from college. She also works on behalf of the Imperial Household, representing the Imperial Family at some official events. Like his sister, she helps her mother with charities.
Princess Isabel, who is a sister of the Head of the Imperial Family, was President of the Brazilian Read Cross, and she's involved with a lot of charities. Her Royal Highness is the seventh in line to throne.
Princess Eleonora, the Princess of Ligne, is also a sister of the Head of the Imperial Family. She, alongside her husband, the Prince of Ligne, are involved with lots of charities in Belgium, where they live. They give special attention to disabled people.
Well, the Imperial Family of Brazil isn't a bunch of hopeless snobs.
Who are these young people being raised to believe in something so hopelessly archaic?
They were raised to keep their families values, just that.
