Something slipped through quality checking here.

The numbers you cite for median income then and now are actually median income vs median wealth. (Also, you got the years backwards--the wealth data is from 2013, the income from 2016/2017.)

To find median income by race, you can find sources like https://www.pewresearch.org/social-trends/2016/06/27/1-demographic-trends-and-economic-well-being/ for a long time base; 2019 numbers are slightly worse than in 2014 (see https://www.statista.com/statistics/233324/median-household-income-in-the-united-states-by-race-or-ethnic-group/).

The difference worsened from black households earning 62.1% of what whites did in 2014, to 59.7% in 2019.

The wealth gap improved, however, from blacks owning 7.8% of what whites did in 2014 to 12.8% in 2019. (It is still shockingly bad! Numbers for 2014 from my first link, for 2019 see https://www.federalreserve.gov/econres/notes/feds-notes/disparities-in-wealth-by-race-and-ethnicity-in-the-2019-survey-of-consumer-finances-20200928.htm)
