Idk, i think borders exist to exclude other groups of peoples. this is why european countries kept splitting up on various racial groups (check and slovaks, all of yugoslavia) Businesses on the other hand would prefer to have access to all peoples. and to have access to cheaper or better labor wherever it is, giving us the success of the european union.
The differences between groups in the former Yugoslavia have little to do with race (as most Americans would understand the term). It's tough to tell the difference between a Croat and a Serb just by looking at them. Conflicts were based more on culture, religion, language, and perhaps something akin to "tribal" identity (not literally tribes but I don't know how else to describe it). Some of these conflicts date back to the 14th century.
The only significant group in the region which some might identify as a distinct "race" are the Roma. That minority lives in all of the countries and they didn't cause countries to split up.

To exclude them from what? That's the question. You give one of the answers here: sometimes people would want to exclude them because they lower wages. But in reality, people who are alarmed by lower wages are rarely in the position to say anything about what happens at the border. The people who get a say about that are the people who are alarmed by higher wages.
