I come from a upper/mid class family and I am the only one in my family that lives frugally. Technically, I don't have to, but I just can't find any joy in material things. As near as I can tell, luxury (think 50k+ $ cars, huge mansions, expensive clothing, jewelry) exists for one and one reason only: impressing others, and in particular, males impressing females in hopes of sexually attracting them. Either that, or people just "going with the flow" without thinking. I cannot come to any other logical conclusion. I've noticed that people buying expensive things don't really want to admit that they are buying it just to show others that they can afford it. If you can afford food, shelter and some medical/dental care, and you can pay your bills (electric, gas, internet, whatever) without worrying about them, I don't think money will improve your happiness. Especially if you need to endure additional stress for it. The Western civilization has it extremely good. If only people read history and truly understood and appreciated what this world consisted of not a century ago, they'd celebrate each day on the streets. Voltaire says that the perfect is the enemy of good, and that's a deep message. I salute these two! If it doesn't bother them, I see no issue with the way they live whatsoever.
