This is a european study that asked some questions to graduating students about their future; you can find it at this address.
I let you read it by yourself, I just wanted to point some interesting things here, that I always supposed but like to see shown in a study:
Page 3-4: German students are expecting the highest salary, but are in one of the most pessimistic countries of this study
Page 5: The French are the most pessimistic about Europe
Page 7: The latin countries tend to see their education systems as bad
And, last but not the least, my employer has a very good ranking :)
