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.
Maybe on the contrary, the richer we are, the more we will pay attention to prices. But with different views and goals. If we are not rich then we look for cheap price tags but quality. But when we are rich, maybe we will much prefer to look at quality first and then price. Or instead we look at the price tag and then match it with the quality.
But maybe if we are at the point where we no longer worry about money, we will start to stop paying attention to the price of small things. But for big things I think everyone will still look at the price tag first.
