The language barrier is a relatively minor issue, in the great scheme of things. The real barriers are on practical matters on taxation and investment, like the VAT situation. While every country is allowed to have fundamentally different tax policies and regulation, there is no real level-playing field. The rules are still too loose.

We need a degree of fiscal integration at the federal level, similar to what the US have. At that point, smart people running smart companies will be free enough to deal with the cultural-border problems just fine.
