"The racial wealth gap is the smallest it’s been in 20 years, under my watch." [...] The ratio of white wealth to Black wealth has indeed narrowed in recent years, largely thanks to rising home values. Black families tend to borrow a larger percentage of their home price than white families, so increasing home prices benefit their total net worth, as the value of the house exceeds the amount of their mortgage. Increasing numbers of Black people are also becoming homeowners, although the rate is still only 44 percent compared to nearly 73 percent for white people. Even more notable is the sharp rise in Black business ownership in the past 15 years, while the percentage of white people who own businesses has remained relatively flat. "More Black small businesses are starting up than in decades. Opening a new business (is) the ultimate act of hope," Biden said in SC.
