I support around 300 Macs for work. In my extensive experience, the deal here is that people are FAR too rough and careless in winding up those charger cables over and over. Apple HAS implemented strain relief here and done their best to make the points of failure less vulnerable. Here's a tip:
Instead of yanking the cable at a 90-degree angle and winding as tightly as possible, let the cable come out of the charger naturally, perpendicular to the charger, make a small loop, and then wind the rest of the cable gently around the two plastic hooks that are provided. If you do this, the charger will last a LOT longer.
The simple fact is that there is no way to make a wire that gets twisted and yanked and bent at a 90-degree angle, and which will nevertheless last forever. That's just not a thing we can do.
Another tip is: own 2 of these chargers, one for home and one for walking around, so that you don't have to wrap up your only charger over and over, every day.
