Wealth—what we own minus what we owe—matters a great deal for families’ economic success. Wealth makes it easier for families to invest in education and training, start a small business, or fund retirement. Additionally, wealth can help families cope with financial emergencies related to unemployment or illness. Through documenting large and growing wealth gaps—such as those between blacks and whites, older and younger families, and top 1% households and everyone else—EPI research makes clear the need for policies that will create broadly shared prosperity.
