In other words, the problem is not that the charger was included with every device you boy. The problem is that a) you buy devices too frequently; b) when you get a new one, you get rid of the old one in such a way that you keep the charger.
Mosen is right, people's habits need to change. If you have too many, why don't you donate the surplus to a charity, for example? Not all charities accept electrical goods because then need to be safety tested which costs them money but some do. I purchased the extra chargers I mentioned above from one such charity shop.
Correct in theory. In practice, as we saw with the Jolla tablet, the price is set and excluding components is a cost saving exercise.
