Not that rich people don't care about their looks. I guess it's just that they aren't concerned about their looks all the time, unless they make a living from their personal image. Rich individuals are usually pretty busy, so they will naturally tend to go through the simplest way to wear themselves to save time and get more comfortable. Meanwhile, someone who is constantly concerned about his looks will have a hard time thriving, because he spends too much money on worthless things, besides not having enough focus and attention on matters which can help him making more money...
Well said mate, people who make money or are business oriented doesn't care much about their looks and appearance because of their numerous busy schedules, they can even be in the boutique to buy some clothes and receive a call about a business proposal they will just discard buying the clothes to attend to business. This reminds me of my life when I didn't have a job, I was literally having time for worthless things that doesn't add value to my life and I think about what to eat and clothes to wear all the time but immediately i got a job it made me become so occupied as I don't even have the time to wear clothes again even when I have a lot in my wardrobe as most of the time am always with my working coveralls and safety boots so definitely people who thinks much about what to wear or eat are literally people that doesn't have something judicious they engage their time with but for those who have productive things they do with their time they don't care much about material things anymore but rather on things that will bring proceeds for them.
You don't have time to care about dressing or eating, that proves you are not rich and not a real rich person. Who told you that rich people don't care about looks, clothes and food...? Did you know that the seemingly simple outfits worn by billionaires like Elon, Gate, Mark Zuckerberg...come from top brands and are even custom designed for them? Don't let their simple appearance fool you into thinking they are cheap. Not to mention, have you seen any rich people riding bicycles to work, renting houses...or do they go to work in supercars, have private helicopters, live in villas?
Don't say that rich people only spend time making money and don't care about their appearance or health. We have never experienced the lives of rich people, so don't be so quick to judge them just because of the images they want you to see on the internet.
I used to have a boss who dressed very casually, he always wore T-shirts and jeans to work and to parties, and that unintentionally made people misunderstand that he was a frugal boss and didn't care about his appearance. But did you know that every t-shirt and pair of pants that people consider normal is worth thousands of dollars? Even his slippers are the same as mine, and I only bought them for a few dollars while his slippers are from the top brand Nike.
