Alfry, I agree with you for the most part.
When you say people are less friendly here, I guess you didn't explain much. Unfriendly doesn't seem to be the right word. So now I will explain a couple of things and then you'll be able to comment.
In the North, families are usually smaller and people like their own privacy. Unless you live in a town where everybody knows anybody, people mind their own business. In the South it's almost the opposite. And when people mind their own business and are always in a hurry, they might look unfriendly, but actually most people are ready to help you... at least where I live
Anyway, we cannot lump things together without discrimination. There are different situations depending on the region, small villages or big cities, in the mountains, on the lake, on the plain...
About the schooling system, a few years ago school has become compulsory until you're 16, if I'm not mistaken. Before that compulsory school was over when you were 14.
