Err. The kid is awake for 16 hours a day. He is applying for jobs in 15 of those hours. This one hour is extra money for him. Also, it is at the same rate as as his full time job pre covid.

There are just not enough new people hiring in India right now. So any extra little money helps.

To your question, who in the world is willing to teach for that low, think of it as his first teaching gig. Through this, he is discovering a new market for himself.
