Two dimensions to rising inequality � Fall in lowest decile income relative to median – particularly in the US � Rise in top decile income relative to median – And top 1% relative to rest of top decile – And top 0.1%... – And top 0.01%... 18
Four Factors driving inequality at top end 1. Celebrity rents Inherent factors driven by Inherent factors driven by 2. Increasing potential for changing patterns changing patterns rapid private value creation 3. Highly remunerated “distributive” activities Sociological / political Sociological / political 4.

David Cameron, Hugo Young Lecture “Research by Richard Wilkinson and Kate Pickett has shown that among the richest countries, it’s the more unequal ones that do worse according to almost every quality of life indicator. In “The Spirit Level”, they show that per capita GDP is much less significant to a country’s life expectancy, crime levels, literacy and health than the size of the gaps between the richest and poorest in the population. So the best indicator of a country’s rank on these measures of general wellbeing is not the difference in wealth between them, but the difference in wealth within them” (November 2009) 25
