■ There is no evidence that the wealth gap could ever close without significant intervention. Wealthallocation policies can close the racial wealth gap, but only if they are coupled with broader policies aimed at reducing overall wealth inequality in the United States.

■ Over the past 30 years, the wealth gap has widened rather than narrowed.

■ A wealth-allocation policy of $500 billion, spread equally across all Black households, could reduce median wealth disparity by 17 percent; a policy of $1.5 trillion could halve median disparity; and a policy of $3 trillion could eliminate median wealth disparity.

■ Focusing instead on mean wealth disparity, a wealth-allocation policy of $7.5 trillion, spread equally across all Black households, could reduce mean wealth disparity by 50 percent, and a policy of $15 trillion could eliminate mean wealth disparity.

■ Given the larger percentage of Black households toward the bottom of the wealth distribution, Black households benefit relatively more than white households by race-neutral allocations. The effect is, however, small: A 30-percent reduction in median disparity would require a total allocation of $9.6 trillion.

■ Equal allocations to all Black households lead to better results for disparity compared with race-neutral policies that use small to moderate total allocation values. However, as wealth-allocation policy grows to include more households, race-neutral policies will have larger impacts on overall disparity.

■ Targeted wealth-allocation policies are better at disparity reduction than their equivalent equal nontargeted policies. Under these targeted policies, median wealth disparity could be halved with a $760-billion policy and eliminated with a $1.6-trillion policy.
