In my opinion it needs a change on several levels for a new European way. We need more democracy but we also need a way out of the laissez-faire economy and we need a common European public or better a common European identity.
A strong parliament is a very important change, but can’t ensure the development of unity, as we see for example in the Iraq or at the Scottish Referendum. As long as there is no common identity, a society will always be threatened to fall apart, if there are any problems. Moreover a strong parliament does not ensure a good policy. The most powerful parliament is useless, as long as the majority of our society for example believes that cheap energy is more important than a clean nature.
Yes, we need a stronger common democracy, a stronger European Parliament, but nevertheless, we should not think that this solves all of our problems in the EU!
