How does the word economy refer to the industrial revolution

Read the following quotes from Helen Keller and answer the question below.

"I am just as deaf as I am blind. The problems of deafness are deeper and more

complex, if not more important than those of blindness. Deafness is a much

worse misfortune. For it means the loss of the most vital stimulus - - the sound of

the voice that brings language, sets thoughts astir, and keeps us in the

intellectual company of man."

"Blindness separates us from things but deafness separates us from people."

Do you agree with Helen Keller’s assessment that deafness is a much worse misfortune than blindness? Explain.
