Bruno Le Maire is the current minister of economy of a G8 country, a post he holds after a career in which he has been minister of agriculture, secretary of state for European Affairs and chief of staff of the prime minister. I will surmise than he has both an idea and hand on experience with how a market based economy works.

You might argue that he is mostly a good politican but considering it's pretty hard to do better as a student in France (ENS, received first at aggregation, ENA), I might hazard that he is probably not a complete idiot either.

And I'm telling you that despite completely disagreeing with the political opinion of the man.
