By 2050, Europe could stagnate at around 500 million people and lose 49 million people of working age between 20 and 64. Arms and brains will be needed to compensate for these asset losses. At the same time, Africa's population is expected to increase by 1.3 billion. This means that the migratory pressure on Europe will be stronger than ever. Europe is not talking about this demographic shock (internal implosion and external explosion) and is not preparing for it. The demographic suicide of old Europe is announced, but there is still time: good prediction is not necessarily the one that is fulfilled, but the one that leads to action to avoid it.
