I am not arguing the utility of having a Spanish HN nor I want to criticize the utility of knowing English. But for some Spanish /Latin American Hackers time is also a constrain and they might not have time to be fluent at a foreign language. Read it, understand it... sure, but fluently writing/talking requires time.

I have been lucky to be born in a region with 2 official languages and more lucky to have a 3rd language in my family and being able to learn English and French in school. But... this is not normal in the rest of Europe.

In any case, I am not sure if I have understood correctly your last sentence. Did you mean "pay maybe more"? I am not sure of what you are implying...
