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.
It depends, I guess.
Lot of rich people don't bother about the pricetag because they can afford it even though they just want it. They don't care about a certain thing, if they want it, they'll buy it, simple as that. They have that kind of mindset since they have plenty of money to the point where they don't know where to spend it anymore. Pricetags at supermarket or in any luxury shop is just a normal thing to them, they don't even bother looking at it.
There are even those who are willing to pay high prices for goods that they don't need, yes... that's a hobby. Someone who has a hobby will easily spend money for their pleasure, they pay a lot of money for their pleasure, it's worth it, isn't it? Seems unwise, but I don't blame it. Even though they have paid attention to the price tag before, their sense of not minding paying a lot for what they want is still at a normal stage, and their hobby will not last a lifetime (in my opinion).
If we don't feel like we are rich, it's a good idea to always consider the usefulness of goods, quality and price when buying products. Also adjust the ability of our human resources to use the product. The price tag matters to people who aren't yet rich, and it doesn't matter to some people who are already very rich.
