What is the average salary of a YouTube scriptwriter?

Sorry my english:

I'm a thirdworld scriptwriter, working up for two YouTubers (thirdworld as well). To be more exactly, LATAM. Each script has 8500 - 12500 words, and the pay is (respectly) 30$ and 40$-45$.

So, I want to know what is the average salary of other scriptwriter from LATAM or others world regions.

Thx
