Part of the problem is the misallocation of productivity. Let's face facts no one needs one more iPhone or whatever gadget but everyone needs good healthcare or whatever basic need. Our current economic system is geared towards providing what in essence are luxury goods, items that we don't need for a happy and healthy life. If our economic system would work towards making basics the priority we would be better off all over the world. That would mean that somehow producing food, or whatever basic need, for everyone would be way more economically attractive and entrepreneurs would create more companies in the food production realm rather than gadgets that ultimately end up in the trash polluting our environment.
