It's a crisis indeed, in which there are alot of short term visions and 'solutions'. Surely you can just drop out, but what about the future? Europe must remember that we are not the only economy around. You can fend for yourself for a while but in the end you must compete with future big economic powers like China, India and South America.
What Europe needs to survive on a long term is a solid platform. A strong network with clear guidelines that stimulates trading, but with the countries remaining their own seperate identity.
To symbolize this in a medium I made a display typeface named EUnity. It's a very complete typeface, that allow all European countries to make proper use of this font. With EUnity, the user is able to connect by choice with the use of uppercast writing or undercast.
The key, it's EUnity!
