If he can afford to send his kid to a private school then Andrew Gutmann must surely know how Google works and could have found these articles (my highlights):
December 2019:
This year, researchers for the National Bureau of Economic Research found that black mortgage borrowers were charged higher interest rates than white borrowers and were denied mortgages that would have been approved for white applicants.
November 2019:
An investigation reveals widespread housing discrimination against blacks and other minorities in New York’s suburbs, more than 50 years after the Fair Housing Act.
October 2015:
North Carolina’s third-largest city, officers pulled over African-American drivers for traffic violations at a rate far out of proportion with their share of the local driving population. They used their discretion to search black drivers or their cars more than twice as often as white motorists — even though they found drugs and weapons significantly more often when the driver was white.
Officers were more likely to stop black drivers for no discernible reason. And they were more likely to use force if the driver was black, even when they did not encounter physical resistance.

It took me ten minutes to find these articles showing indisputable evidence that in policing, banking and real estate, there is systemic racism.
And on top of that, there is the issue of the compounding effects of systemic racism that looted black wealth prior to the 1960s and left a legacy of immiseration.
If you don't believe there is systemic racism NOW it's because you are refusing to look or you don't wish to believe it.
