Fifty 'countries' with virtually no limits of movement between them, (and almost everyone larger than New Zealand), makes the US an interesting place to test some economic ideas.
Harvard professor, Edward L. Glaeser, has been trying to understand the population movements from the higher-income coastal regions of the Atlantic and Pacific to the lower-income centre and south. He argues, it can't be "the weather" - temperate California has a much better climate than Texas.
These migrational flows are important - and have a strong political impact. They represent a shift from liberal to conservative regions. Coupled with a relatively high birth rate, an ethnic shift away from WASP domination, and strong immigration flows, the US population will stay young for the next century, and it looks like it will become more conservative.
Glaeser has an idea about why this is happening - and it has a lot to do with affordable housing.
He concludes that "housing policies, determined often at the very micro level, are shaping the future of America."
"Perhaps, those ... enemies of local growth might recognize that their policies have consequences, including reducing housing affordability and encouraging the flow of population to places like Texas."
In New Zealand, we don't have such a relief valve - all local authorities here have similar tight restrictions - so the only option Kiwis have is to leave the country. Perhaps they are not going for 'higher pay'. Maybe they are going to get access to the prospect of more affordable housing?
