Different is not a value measure. If they like it then bully for them. However one size doesn't fit all. These countries are much more socialist than we have ever been. They have developed their social programs over centuries and have historically been much more centralized than us. They stared as kingdoms where the king was the center of power and law. As they evolved to parliamentary systems , parliament assumed the king's power. They are also smaller; in size more analogous to our states and easier to manage. Look at the issues they are having in the ECU integration. We have had a federal system where much power has been invested in the states. Each state has a different history and demographic. I don't think it's a good policy to have central control of such a large portion of our economy in Washington DC.
