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.
But there are few rich people who don't really like to spend their money on random things, they like investments and businesses, so they can have more money to spend on things they wanted to have in the future.
I agree, it really depends on the person on how they spend their money. But some of them are the same as the second you mentioned. Rich people spend wisely, they only use their money for the things that can bring them money, and also for their daily needs.
