At the end of the day Chinese worker A put in 40 hours of work and American worker B put in 40 hours of work.
They both invested 40 hours of their life into the project and neither of them are ever going to get that time back. Both of them will die at roughly the same age.
Just because someone lives in an area of the world where it's cheaper to live doesn't mean he should accept lower wages.
The American has enough money to take the family on the annual pilgrimage to Disneyland or Dollywood. The American has a car with A/C and an automatic transmission, shops at grocery stores that source produce and goods globally, and can have four bathrooms with potable water in its house.
To do the same in India, China, etc., you're not making it happen on the $800 per project unless you have a farm of people living in their grandparents' house and riding a bicycle made of cast iron and bamboo to get rice and something to "flavor" it.
