Citizens have been protesting in Europe against planned chances that are made to make economical situation better than it is, and personally i have to say that those planned changes are important to be made. There is for example changes to keep the European economy in good level in competition against other areas in the world.
Personally i think that the level of salary raises should have been more realistic like ten years ago if not earlier. Over ten years for now there have been salary raises that have no realistic base in real live. without these raises companies in Europe would have been in way better condition what come to they're economical situation. And even more so with the fact that without those raises they would have get much more orders from around the world with more reasonable prices.
People are often against changes that would only protect them from very expensive mistakes. If those peoples would get everything they want, they're employers and governments would be in bankruptcy very soon. That would leave them with practically nothing but some people often forget that fact.
Demonstrators in Brussels have been trowing rocks against riot police, and police have being trying to calm them down with water cannon and pepper spray.
But anyway, those changes in Europe are the kind that is needed to make economy better in there.
