Wasting money buying phones every year just to be trendy is awful. I think we should learn how to save the money we get from different sources because we are teenagers so we don't earn that money. It's hard not to go with trends as a teenager because if you don't go with them you'll be considered boring. The new generations should be taught how to manage money and how to be liked for their character, not for the things they have on them or what kind of phones they have.
The prices of brand new products are very high, that's why teenagers think that if you have one product that is very expensive you are cool and should stay around you. Even if it's not necessary to buy all those expensive things, people will buy them for approval from others.
