For germany I feel confident to claim that any projections you could make about ROI should more than warrant it.
I have a suspicion that Americans tend to underestimate Germany, thinking of Europe as something that might be comparable to the US, and Germany as only a small part of that.
In reality, Germany has 80 million people - similar to California, Texas, and New York state put together, and is as you say the world's fourth largest economy.
They also much prefer German over English, so it might well be a good investment for many startups to have a German English student translating their site.
