Thank you for your question. I believe that the EU is founded on equality between its member states, with 1 member 1 vote being the norm since the EU's foundation. I don't think this should change. The disproportionate spending is, as my friend Antoni pointed out, because larger states will use more services than their smaller neighbours. This spending only amounts to 0,1% of each nation's national budget.
I do however think that there should be a sensible level of spending. 0,1% of national budgets is a sum we should never go over with any big projects or anything else. I don't believe that the EU level , is the place for far-fetched and expensive ideas such as a pan-European railway. That's up to member states to do on a bi or tri lateral basis. This is why we need to define the areas that the European Union can legislate on. These projects that would disproportionately take money away from the richer nations of the EU should never have been allowed to be proposed, and would not be under the EPA's plan that I have sponsored for more definition of the EU Council's powers.
