A huge wealth gap has opened up between black and white people in the US over the past quarter of a century – a difference sufficient to put two children through university – because of racial discrimination and economic policies that favour the affluent.
A typical white family is now five times richer than its African-American counterpart of the same class, according to a report released today by Brandeis University in Massachusetts.
White families typically have assets worth $100,000 (£69,000), up from $22,000 in the mid-1980s. African-American families' assets stand at just $5,000, up from around $2,000.
A quarter of black families have no assets at all. The study monitored more than 2,000 families since 1984.
"We walk that through essentially a generation and what we see is that the racial wealth gap has galloped, it's escalated to $95,000," said Tom Shapiro, one of the authors of the report by the university's Institute on Assets and Social Policy.
"That's primarily because the whites in the sample were able to accumulate financial assets from their $22,000 all the way to $100,000 and the African-Americans' wealth essentially flatlined."
The survey does not include housing equity, because it is not readily accessible and is rarely realised as cash. But if property were included it would further widen the wealth divide.
Shapiro says the gap remains wide even between blacks and whites of similar classes and with similar jobs and incomes.
"How do we explain the wealth gap among equally-achieving African-American and white families? The same ratio holds up even among low income groups. Finding ways to accumulate financial resources for all low and moderate income families in the United States has been a huge challenge and that challenge keeps getting steeper and steeper.
"But there are greater opportunities and less challenges for low and moderate income families if they're white in comparison to if they're African-American or Hispanic," he said.
America has long lived with vast inequality, although 40 years ago the disparity was lower than in Britain.
Today, the richest 1% of the US population owns close to 40% of its wealth. The top 25% of US households own 87%. The rest is divided up among middle and low income Americans.
In that competition white people come out far ahead.
Only one in 10 African-Americans owns any shares. A third do not have a pension plan, and among those who do the value is on average a fifth of plans held by whites.
Shapiro says one of the most disturbing aspects of the study is that wealth among the highest-income African-Americans has actually fallen in recent years, dropping from a peak of $25,000 to about $18,000, while among white counterparts of similar class and income it has surged to around $240,000.
In 1984, high-income black Americans had more assets than middle-income whites. That is no longer true.
