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.
People without looking a tag don't care too much about the money because they afford it already but some of them have a different story, some of them are already rich enough so they dont take too much affected on the price, and some of them just really care about the hard work earned money so they spend those wisely because they know how to get give time and effort to have this amount. It depends on the person how they handle their money its nothing if you are rich now but you are not financially literate soon if this continuously happens spending not wisely they will lose that money I'm not saying this always happens but it happens.
