Systemic racism is when only 1% of the Fortune 500 CEOs are black despite the overall black population being about 14%.
I think that you need to prove that is systemic. It could be, but as stated it is just a statistic.
For example, one could argue that systemic racism is the disproportionate percentage of unarmed black men killed by the police when we consider the racial makeup of the nation (when we consider the racial makeup of unarmed people killed by police then white men are the majority). This is the argument of BLM. Black men make up a minority of citizens, but they are disproportionately killed by police.
The fallacy is apparent when we consider that black men, although a minority, are disproportionately committing violent crimes, that police (regardless of race) are almost 20% likely to be killed by a black man, etc. So race may or may not be the cause (it is taken for granted it is because it fits a certain narrative).
Likewise, you need to prove that the disproportion of black CEO's are a result of racism. I suspect, given the median age of CEO's (58) that there are other factors. Consider affirmative action. Minorities were afforded opportunities that that were intended to "level the playing field" based not on merit alone but on race. The perception, and perhaps the reality, is that minority graduates may not have met the same educational requirements as comparable white graduates. The degrees are the same but there is at least a perception that they do not represent the same level of competency. This was why Clarence Thomas said he does not display his Yale degree - the year after he was admitted affirmative action came into play and devalued his education even though he did not benefit from the policy.
And there are consequences of past systemic racism. Many of the times CEO's gain a position from reputation (or family reputation), have benefited from educational opportunities, wealth, etc. gained by their parents. But this is not systemic racism. It is the consequence of past systemic racism.
So you may be right - BUT just stating facts does not prove you are correct about how those facts came to be.
