"The world is looking at a debt crisis that will span the next 10 years and it’s not going to end well, economist Arthur Laffer has warned"
You lost me there. The famous Laffer curve is empirical nonsense, why should anyone trust the author here, and what are his motives?
If birth rates are quickly falling, the debt will have to be repaid by an always smaller population, it seems it will make matter worse. (Unless we find out a magical productivity gain that can be heavily taxed by government)
