Managing demographic ageing and decarbonising the economy will also require major efforts in the coming years. The infrastructure needs both to be adapted to a post-fossil age and to meet the requirements of an ageing population. The education system also needs investment to deliver significantly better results in the future. New concepts must be developed in order to ensure prosperity in this country. The state plays a key role in all these tasks. It can indirectly stimulate private investment with its own investments, and it can provide favorable conditions and appropriate support measures for private investors.
