I often read people saying they want to earn enough money so they don't have to look at price tag of product. Imo, even if you are rich you wouldn't want to spend money on things that are not worthy of price being paid.
You wanna look at product and then it's price, if it's worthy of price, you purchase the product.
The choice of many rich people is due to the need for job specifications, they buy things such as perfume according to their needs, perhaps because they don't feel confident if they use cheap things because of the influence of their circle, even if they go to a food theme, if they go to a restaurant, they choose a luxurious design. The downfall of those who are rich is that they sometimes prioritize prestige because they have to use luxury items and when eating, the variety of food must be extravagant and the choice of place is also exclusive.
So sometimes what they do is a bit excessive if we look at it. But personally, when I buy certain items, I pay attention to their use and quality, if the price is right, I buy them.
