It's interesting to see the EU take form. With the recent finance reforms and articles like this, it looks to me like the EU is becoming more and more like the US with the countries taking the role of states. Moving between US states for the purpose of employment is extremely common. The EU countries have more border autonomy and language barriers that prevent people from moving between them, but it seems similar to the formation of the US and the subsequent 200 years of consolidating power at the federal level. I'm looking forward to seeing what happens in the next 20 years.
