8. Mario Draghi
The President of the European Central Bank is another powerful person in 2015.
Imagine how a day of his life goes. Basically he spends the entire day talking about monetary minefields.
However, one wrong step from him and the European Union and global economic growth for the foreseeable future could be damaged.
Not long ago Draghi announced a massive bond-buying program of a trillion Euros to resurrect the European economy.
But because it worked in the United States doesn’t mean it has to work in the Europe. We will live and see how that goes!
