They're not committing suicide because of the low pay. Nobody is forcing them to take the job so I don't think being paid triple the money would do much to lower the suicide rates. It's the job itself that's making them kill themselves. They can't handle the working conditions or the work itself.

Work that requires you to do one thing 5000 times a day shouldn't be done by a human anyway.
