When it comes to the EU I think the european people must demand certain equalities. We need equal social standarts, equal tax-policy, etc....
To achive this we first need legal equality. The National states must accept they need to treat all european citizenships equal. This can only happen if the suverain, that's the people, not the governments; agree on a european constitution.
Should we have a european constitution we need to resist against national governmemts negating it.
