Every year there are new phones and if we fuel our wants always then we have tons of phones and it would be useless as we ain't using them or worse you wouldn't have any savings at all.
I think everyone needs to choose between a lifestyle that meets their daily needs and one that continues to be used in the long term and this applies to everyone. Be it rich people or poor people, because when someone always prioritizes their lifestyle every year by continuing to follow updates on expensive goods that can give them a luxurious lifestyle. One day that person will also be poor if he doesn't care about his income because he feels he is rich and won't fall into poverty again, whereas a poor person would be very silly if he followed this, especially if the poor person doesn't have any savings.
The more money you have, the more you spend. That is why having the mindset of saving first before spending is best mostly if your income is big so that it is sure that youll be saving some money and not only in wants.
If you see a person who has a lot of money, but he also spends more of that money, that means he doesn't have a mindset for saving except just a mindset to keep spending until there's nothing left. And usually such a person will not easily become rich or gain long-term comfort in his life because when he has no money, he will always face difficulties himself. So I also quite agree with your suggestion on the point of saving not only for our living needs, but also for other things.
