In 1992, just a year after Greengrass was born, the Ho-Chunk Nation began to operate a baby bond-style program, the Child Trust Fund Program, financed by revenues from the tribe’s casinos and known colloquially as “18 money.” Zewde studied the impact of a baby bond program in growing the average American’s wealth and narrowing the racial wealth gap. Greengrass said a baby bond program alone is not enough to narrow a racial wealth gap, as wealth has accumulated for generations.
