Bolivia has half of the worlds reserve of lithium, in this desert. But president Evo Morales doesn't like foreign mining companies in his country, for historical reasons. "We will not repeat the historical experience since the fifteenth century: raw materials exported for the industrialisation of the west that has left us poor", as Bolivia's minister for mining, Luis Alberto Echazu has stated. That would not be a problem if their interest were to ship as much lithium as possible to battery-manufactories, but they have no interest in that. They are going to start mining in a very slow pace as explained here and here. If they ramp up production, and the world started to be flooded with high quality lithium from Bolivia, the price of the lithium battery sure would drop. This is why Elon Musk must send mr Morales a brand new car so that he can see what a brand new world his poor country could be part of making.
