These stories are so common, when I read it, I was thinking it was a precise description of my own brother. My brother who earns 6 times less than I purchases a 1000$ Samsung phone whereas I don't buy any phone at all and just use the handme-down from my wife, for 0$. It's a 5 year old iphone6 but still works Great. His other expenses are much lower though: for example, he has subsidized housing which means he pays almost nothing for rent. and he has no car, since he can bike to work.
Advertisment almost never works on me, so it's hard for me to imagine it's so effective on everyone else.
