Except those data are wrong. Germany's per capita GDP (and this includes backwards formerly communist areas in East Germany) is comfortably above Mississippi's. About $10,000 per year using PPP (Purchasing Power Parity). For the Netherlands (which doesn't have a backwards formerly communist area to weigh down the national average), the difference in per capita GDP versus Mississippi is about $15,000.
From where I sit the European Socialists are easily outscoring Mississippi. And Oklahoma. And West Virginia. And Arkansas. And Alabama. And Kentucky. And Louisiana. And Tennessee.
And so are all those socialist blue states.
Scoreboard don't lie!!
