That's quite terrible argumentation. High degree of corruption is problem of all post-socialist countries, from Russia to Albania, and absolutely not related with being balkan or not.
As for nationalism, are Hungary, Czech Republic, Slovakia, Poland, and lately Austria part of balkan too ? Because their governments are several degrees more nationalist than current croatian is (please check their offical stance towards non-European immigration and compare it with Croatian). If you aren't aware, current centre-right government of Croatia formed coalition with left-liberals, who are complete opposite of nationalist.
Leaving the country to survive ? Oh, I see, than million of Spaniards, southern Italians and Poles are balkanites too, aren't they ? Social problems you are talking about have no relation with cultral and historical belonging to balkans, which you again reduce to povertry and backwardness.
Quite prejudiced, I'd say.
For your last sentence, have you learned history ? For you understand fundamental differences between Byzantine and Frankish state concents ? Are you aware, Croats grew from former Frankish vassals to their indipendent Kingdom ? Do you understand, our state and political traditions differ radicaly from, Serbian or Bulgarian ones ?
I need to know do you posses basic historical knowldge before continuing debate with you.
