Most people would let their desires win due to comparison to the other people, cause if they are contented of what they had, for sure they could save money with taking loans and withdraw savings just to buy unnecessary things that can't help for your own convenience. Focusing in investment rather than comparing would build up the mindset of "in the future or sooner I would also afford that" which is actually good cause for that term you could be financially stable to buy things you want.
I agree with this. When a person has a lot of money, he becomes a slave of money. He starts buying up apartments, cars, jewelry like crazy. But he doesn't have time to use even a small percentage of it. He just needs it very much to make dust in the eyes of others.
