If the chatter thought the job was so bad, they can quit and get a different one. Millions of people make that choice, it is available to them. There is no requirement that they do this work; it is entirely voluntary. The people doing these jobs have determined that it is the best option for them, personally, or they wouldn’t be there.
PS: $2-4/hr is a more than decent wage in the Philippines. Median income there is $2.11/hr, minimum wage is $1.36/hr.
