What I believe is that today's generation have easy access to all the luxuries of life which is being consistently provide to them by there elders. This comfortable access to everything has really spoiled them because they are taking everything for granted, getting influenced by the luxurious and costly things which they see on social media, they get after it and want it at any cost.
During the time of previous generation, there was not that good access to everything we really needed to work hard and then get some hard earned money, so we had an Idea that it's not easy to use that hard earned money so quickly and easily but rather save it for future purposes and spend as much required and moreover at that time I don't think there was any sorts of competition for showing off your luxuries, everyone lived a good and normal life.
The example of that girl is because of this case only, she's getting influenced by others luxuries and want it in her life as well and maintain a level and status but she's forgetting that all these things are just for short run, in the long run what matters is the money which you saved carefully and can help you in every situation either worst or best because you never know what's going to happen tomorrow, so you need to be ready and causious..!!
