As an illustration, households’ net worth in France is five times higher than GDP and it has grown by over 7% on average per year and in real terms between 1997 and 2007, compared to a 1.7% increase for GDP (Conseil des Prelevements Obligatoires, 2011). Taxing wealth at a rather low rate should thus generate large and rising tax revenues. Second, real estate accounts for a large share of household net worth (Fredriksen, 2012) and the tax can thus hardly be avoided. Third, inheritance and gift taxes, not only on immovable property but on all net assets, could offer an alternative to the taxation of lifelong saving.
