Netflix has the translations, they are just not provided for you. For example, Germany has usually both English and German subtitles available for all content.

Netflix has the translations, they are just not provided for you. For example, Germany has usually both English and German subtitles available for all content. My best theory is that Netflix pays for certain regions, and worldwide subtitle distribution would cost more. That sounds ridiculous though when comparing to the content itself, but what other reason could there be? The simplicity of the user interface?
