It is legitimate to tax effort-unrelated rents

Many euro-zone countries are now going to struggle with their public finances, due to the slowdown in growth, spending on support for purchasing power, support for reindustrialisation, healthcare, defence, etc. There is a way to reduce fiscal deficits at a time when debt interest payments are rising rapidly: tax effort-unrelated rents. Such rents may come from: Abnormal rises in commodity prices; Realised capital gains thanks to expansionary monetary policies; Monopoly (dominant) positions.
