C is correct. To measure income inequality, OECD follows throughout time the evolution of the ratio between the income received by the 10% of people with the highest income to income received by the 10% of people with the lowest income. A growing ratio shows growing income inequalities. Inequality increases according to OECD with globalization, skill-biased technological change, and changes in countries’ policies. Also according to OECD, income inequality contributes to the “squeeze” of the middle classes.中产有钱了不是消费就提升了么
