"1) First of all, demographic decline. No one seems to be concerned with this fundamental fact. The burden of older people and the lack of young people are automatically going to produce the following phenomena, which are already beginning but are only going to speed up: the impossibility of paying for retirements and social benefits, the brain drain, and a shortage of creators and innovators. Taxes and burdens, like public debt, will keep on growing all the way to a breakdown. The policies of the European states are not taking these facts into account. Bankruptcy looms. Countries whose population is ageing and declining can no longer be sure of a minimal level of innovation."
