In response to comments.
I believe that those of us who have been financially successful, through a (varying) mix of effort and chance owe a lot to the society in which they have grown and lived. (A view I share, with all due respect, with Warren Buffett, Bill Gates and their Giving Pledge initiative; they are not known to be extreme leftists)
For the most part, the French tax system is very progressive, and the rich pay high taxes. But I believe that this is not the case today for many of the very rich. I believe that this is wrong, and politically explosive, especially so in an environment in which the state must reduce its spending.
I have examined various options to achieve that goal. I have concluded that, although far from perfect, a Zucman-like tax seems like the least bad way to do so (although, as I have discussed with Gabriel Zucman and stated elsewhere, I believe 1% is more realistic than 2%). This is why I have endorsed it.
(Let me also add something else. Again said elsewhere, but needs repeating. Even if relatively successful, the Zucman tax is not the solution to reducing the deficit. At most 20b , more likely half that, compared to a 120/150 b adjustment (over a number of years)
