If black families were as rich as white ones, U.S. economy would be $1.5 trillion bigger

• The typical black family in America has one-tenth the wealth of the typical white family—and that gap has been widening since 2004.
  
• Closing the racial wealth gap would add $1.5 trillion to the entire U.S. economy, according to a new report from McKinsey.
  
• "This is not something that affects only one community," the report's author said.

The typical white family in America has 10 times the wealth of a typical black family—a figure that has barely changed in two decades and has actually widened in the current economic expansion.

This persistent, and growing, disparity has become a pressing issue for Democrats, with four presidential hopefuls making their case in June at the Black Economic Alliance Forum and a House Judiciary subcommittee debating reparations for slavery just this summer. 

But it's also infiltrating corporate America. The consulting firm McKinsey this week issued an estimate of just how much the historic and current discrimination against African-Americans is hurting the broader economy. That estimate: Somewhere between $1 trillion and $1.5 trillion.

If black families were as wealthy as white ones, in other words, America's economy would benefit from the addition of "between 4 and 6 percent of the projected GDP in 2028," according to the report.

This gap shows itself in many ways. The most valuable possessions the bulk of Americans own is their homes. But black Americans, who were kept out of homeownership by local and federal policy through much of the 20th century, are much less likely to own their homes today. When they do own, black Americans disproportionately own houses in poorer neighborhoods with lower home values and get less favorable mortgage terms than white Americans.

"The racial wealth gap is a reflection of long-term policies and practices by both the public and private sectors that have systematically disadvantaged black, Latinx and Native communities in favor of white Americans," Nina Banks, a professor of economics at Bucknell University, said via email. 

As the Atlantic reported this week, federally sanctioned farm policies throughout the 20th century dispossessed 1 million black farmers of their land. Black people today have more college debt, less access to banking services and lower pay than their white counterparts. 

All this contributes to the state of affairs in which the typical white family is worth about $171,000, while the typical black family is worth $17,600. And because the wealth (or poverty) Americans are born into determine their earning power, wealth inequity carries across to incomes, with white Americans earning $1 million more over a working lifetime than their black counterparts.

This doesn't hurt just black Americans, McKinsey said, but creates an overall drag on the economy. The upside is that reducing that inequity is likely to be an overall positive on the economy, said Jason Wright, a partner at McKinsey and one of the authors of the report.

"That's not just the money in black pockets, that's the entire economy — dollars in the hands of African-Americans, being distributed to people of all types, all businesses, all over the country," he said.

The fact that an elite corporate consultancy is taking up an inequality issue long relegated to nonprofits and community activist groups has caused a bit of surprise. 

"It's an interesting moment that a group that most of us would think of as pretty mainstream and not having any particular agenda on this issue is highlighting it," said Sam Brooke, deputy legal director for the Southern Poverty Law Center's economic justice division. "The fact that they're taking it up shows how nonthreatening and beneficial to everyone these proposals can be."

However, Brooke went on, closing the gap won't happen without targeted policies—something unlikely to happen in the current administration, he said.

"We continue to see policies that are put in place that continue to have a disparate effect on black Americans," he said, including efforts to restrict access to public housing for people who have criminal convictions, as well as to make it harder to bring cases of housing discrimination

"This is also an issue that government needs to get behind on. It's not something that we could look to the private sector and say, if only there were access to good [interest] rates, we would fix this."

Banks, the Bucknell professor, said it was "noteworthy that the issue of the racial wealth gap has been taken up by a mainstream consultancy," but added that the central concern should be on achieving racial equity—not economic benefits.
