Charles Kenny explains to what extent the country you live in affects your livelihood:
[P]overty in Africa and Asia isn’t the result of something about individual Kenyans and Pakistanis, it is instead something about Kenya and Pakistan. Individuals the world over have the same drives and capacities, but the societies and places in which they live present radically different opportunities to turn that drive into wealth, health, and well-being.
That’s clear from evidence compiled by Princeton economist Orley Ashenfelter for the National Bureau of Economic Research. He looks at the wages earned by staff working at McDonald’s franchises around the world and compares what they earn to the cost of a Big Mac in that same franchise. The Big Mac is a standard product, and the way it is made worldwide is highly standardized. The skill level involved in making it (such as it is) is the same everywhere. And yet McDonald’s employees worldwide earn dramatically different amounts in terms of Big Macs per hour.
In the United States, a McDonald’s employee earns an average of $7.22 an hour, and a Big Mac costs an average of $3.04. So the employee earns 2.4 Big Macs per hour. In India, an employee earns $.46 an hour. The average Indian Big Mac (made of chicken, which is cheaper than beef) costs only $1.29. Still, the employee earns only one-third of a Big Mac for each hour worked. Same job, same skills—and yet Indian workers at McDonald’s earn one-seventh the real hourly wage of a US employee. There’s a huge “place premium” to working in the United States rather than India.
The place premium affects more than just low-end service jobs. Economist Michael Clemens, a colleague of mine at the Center for Global Development, studied a group of Indians working in an India-based international software firm who applied for a temporary work visa to the United States to do the same work in the same firm, just on the other side of the Pacific Ocean. Some of them then won the lottery by which visas were issued, while others lost. The winning workers, who were still in the same firm and still doing the same type of job on the same projects, suddenly saw dramatic differences in their pay.
The ones who moved to the United States started earning double what their colleagues back in India were earning (adjusted for purchasing power). They were earning more not because they were different from the colleagues they left behind—selection was not based on education, talent, or drive but was entirely random. And once they returned to India, they went back to earning pretty much the same as their colleagues who had never left. They briefly earned more in the United States simply because they were in the United States rather than India. (source)
Some more numbers are here, regarding how much more workers in the U.S. make compared to identical workers in developing countries; e.g. Nigerians and Yemenis stand to gain upwards of 10 times as much from moving to the U.S.
The place premium is a strong argument in favor of reducing migration restrictions: it doesn’t seem just that people’s income is determined by the good or bad luck of having been born somewhere, and the use of force to keep people in their country of birth only aggravates the injustice. However, by the same logic we can also argue for a more generous welfare state: it’s not just your country of birth that affects your income. Your parents, social class, genetic endowment, health prospects, looks etc. are also a lottery that affects your income and good fortune.
