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.
I am pretty sure this only goes for those who are born into riches. Everyone who had to earn their riches is probably more stingy with their money than the average person. Because they know the worth of a dollar more than anyone. So they definitely look at the price tags. The ones who do not know the worth of a dollar and have rich parents spoil them their entire lives are not going to look at price tags. But that is not a symptom of them being rich but rather them being the subjects of bad parenting.
