Son of brazillian millionaires here. My parents own a relatively large local clothing company, nothing massive nor impressive really, but enough to make "good" money and allow me to live as a NEET for the rest of my life. I will inherit the company, but I plan to live off of rents from real estate investments my father has made.
I don't live an extravagant life for I do not enjoy such things, I have my own apartment, a simple two bedroom apartment, which I have converted one of the rooms into an office/library where I read and study linguistics, a large living room and a nice indoor garden.
I have a car which I seldom use and an electric bike that I ride to and from the local market.
I stay inside most of the time, reading, playing videogames and smoking my pipes, I have a cat that keeps me company but thats it.
