Here's the theory on people who work for a bank and blog for fun. Do they think of themselves as bankers or bloggers?
It boils down to their Ginis. You see, some people have magic lamps inhabited by blue-suited banker Ginis, some people's magic lamps have sailor-suited Ginis... :)
Actually, a Gini coefficient is a measure of statistical dispersion, and is a standard measure of income inequality in a society. My take is that people from more unequal societies are more likely to define their identities in terms of who they are at work.
Why?
Imagine a relatively well-off person living in an obviously unequal country. He needs to make peace with the fact that he lives a comfortable life, but the people from the slum/ favela/ ghetto/ council estate/ inner city live obviously miserable, abysmal lives. The sheer presence of that abyss, the unspoken fear and guilt that that abyss evokes, pulls at the psyche of the comfortably-off like gravity. The psyche protects itself from that pull by believing that privilege and comfort are deserved, earned, by hard work, by education, by qualifications, by seriousness.
In this unequal context, it is hard to think of oneself in purely frivolous terms. It feels like being the surfer on the beach in Apocalypse Now. Its the reason why cricket in India or football in Mexico are not just silly games played for fun, they are about the redemption of national pride.
So what do I expect to observe in the data? I expect people from more unequal societies to wrap their identity ever more tightly around their professional selves.
Here are Ginis for some of the OECD-30. Their rankings are:
1. Mexico: .474
2. Turkey: .430
4. USA: .381
7. Great Britain: .335
8. New Zealand: .335
12. Canada: 0.317
The two most unequal OECD members are Mexico and Turkey. Fortunately, I have friends from Mexico and Turkey who tell me their compatriots unambiguously define who they are in terms of who they are at work.
Also, to my earlier observation, Britain's Gini is the same as New Zealand, and is a lot lower than the USA. Canada is even further away from the USA than is Britain. So if the theory holds, Canadians should be a less likely to derive their identity from work than either Americans or Britons, despite Canada's stereotypical cultural location somewhere in-between the USA and Britain.
India is not in the OECD. So I looked up the World Bank's Ginis metrics, which show that India is better (i.e. more equal) than the USA.
While that is flattering, and says something important about the world's only superpower, the World Bank might be systematically underestimating South Asian inequality. Pakistan looks really good on the same metrics, more equal than the Netherlands, Canada, France or Switzerland. That doesn't ring true. My hunch is that India really is in the mid - 40s pack, along with Mexico, China, Jamaica and Turkey.
A more classical theory, which involves no melodrama about the gravitational pull of the abyss, is the impact of marginal tax rates on labour supply. More equal societies have higher marginal tax rates. People therefore have less reason to work hard to earn money. They therefore invest more of their time, and identity, in leisure rather than labour.
I buy into the conventional theory, but it doesn't quite feel complete. Maybe that is because I remember an India with high marginal tax rates, in Indira Gandhi's time, when people still wrapped their identities around their work, even if they didn't work especially hard. The ways in which people construct their identities change more slowly than tax policy.
