This just isn't true, as long as there's repair shops out with a sizable customer base. The issue is companies do everything in their power to make it impossible for that service to exist. It also largely depends on the economy; If the economy is great, people throw their old stuff away and buy new stuff. If money is tight, they repair it, and if there's an economic collapse they let it stay broken. I wonder where we are?
Unfortunately, it depends on the mentality. My well off friends often pay good money up front to buy the latest and hold onto a device(smartphone, laptop, sometimes tablets etc.) for 5-7 years.
My less well off or broke friends show the opposite, they often go out of their way to take debt(contracts, installments, pay later etc.) and continue upgrading to latest phone/watch/tablet/fitness tracker every year. It feels like that there is some kind of overcompensation combined with FOMO involved.
I don’t want to generalise this, but I had known probably a sub three figure people from my childhood and have seen this same behavior repeated always.
One of my friend in marketing told me that, people buy dreams, and hope that a new dream will help them forget the nightmares/problems, hence all adverts often include happy smiling beautiful people or conveys some form of freedom, prestige, social status …
Just a thought.
