Greek Prime Minister Kyriakos Mitsotakis: Fearfully, there is no country in Europe that has truly addressed the demographic problem at its root. You see countries with very developed welfare states — the Scandinavian countries — and they face similar issues. Hungary spent enormous amounts of money on demographic policy, also for political reasons, and it largely failed. There was essentially a small increase in births for one year, and then births returned to a downward trend.
