 Thank you very much for being with WPC TV. You are a very prominent economist. You've assisted a lot of governments in France and now you're, I think, head of strategy for the government of Manuel Valls. And now you've just been to sort of, difficult job. Now you've been talking about inequality and globalization. Is there an acceptable level of social inequality, social mobility, immobility, if you like, going with inequality? Somehow, I mean, the more social mobility you have, the more inequality is acceptable. Because, you know, what's very difficult to accept, whatever the judgment you have and the desirable degree of equality within the society, that it perpetuates from one generation to next. So I think we still don't have a very good approach to that. I mean, people focus much more on inequality because it's easy to measure or relatively easy to measure. It's more visible. But the question of what happens to children and what happens across generations is very important. One of your colleagues brought up at the last moment, inheritance tax. What's your view on that? Oh, as an economist, I think it has very desirable properties. Inheritance tax does not affect significantly the behavior of individuals. Inheritance tax avoids the situation in which people live out of their rents. So it gives an incentive to people to make the best of their skills. So it is desirable. Now, the politics of the inheritance tax is difficult. I think it's difficult in many countries and difficult for reasons that have to do with the fact that, you know, people who have worked hard wants to leave something to their children, even if it's not in the best interest of their children, because I would certainly prefer my children to work and to create rather than to live out of my wealth. I may leave to them. They won't be able to anyway. Your co-pagin, Thomas Piketty, went, I think, one step further advocating a wealth tax of what boils down to a wealth tax. Would you go that far? I think a wealth tax also, you know, we have wealth taxes on land. Economists prefer taxes that do not affect the behavior of people too much. So wealth, that's something that you may wish to tax with it, not too high a level, obviously, because it may not affect the behavior too much. What you don't want is a situation in which people would be distracted, I mean, refrain from working, creating, because of taxation. The wealth there is, that's different. Now, you have to be careful also in terms of the return on investment, especially on risky investment, because if you take the wealth tax post, people have taken risk, it may affect the risk return calculation, and ex-sante may affect the willingness to take those risks. So that's something you have to be careful about. Jean-Pierre Sainte-Ferri, thank you very much. Thank you.
