Income inequality is increasingly acknowledged as a key economic issue for the world. The topic is a major theme at Davos this year. Economic inequality is also an increasingly common topic in U.S. politics.
A new study has found that economic mobility does not appear to have changed appreciably over the past thirty years, even as the wealth gap has grown enormously. The authors analyzed the probability that a child born into the poorest 20% of households would move into the top 20% of households as an adult. The numbers have not changed in three decades.
On the other hand, there is clearly a substantial accumulation of wealth at the top of the socioeconomic scale. The richest 1% of Americans now own 25% of all of the wealth in the U.S. The share of national income accruing to the richest 1% has doubled since 1980. In contrast, median household income has shown no gains, adjusted for inflation, since the late 1980’s and has dropped substantially from its previous peak in the late 1990’s.
Why is this happening?
