If America is systemically racist why do Ghanian Americans earn more than White Americans?

As part of the big lie that America is systemically racist the Democrat party's platform declares that the median income of minorities is lower than that of whites.

But that's not the case as this chart shows:

Ghanians and Nigerians are Black.  Yet they earn more than white Americans.

Clearly that shows that America can't be systemically racist.

In a systemically racist society white people would earn more than anyone else but that's clearly not the case.

Indian Americans earn nearly twice what white Americans do and they're brown skinned.

What this shows is that America is a land of opportunity not a racist hell hole.

Black Americans have lower incomes not because of society racism but because of Democrat racism.

It's the single parent Black families created by Democrat welfare programs that are a major part of the problem.

But the fact that Democrats allow Blacks to live in unsafe neighborhoods where thousands of Blacks are shot each year, in Democrat run fiefdoms like Chicago, is a major contributor too.

As is the fact that the public schools in Democrat run cities fail to educate Blacks and the Democrats refuse to allow Blacks to have school choice so their kids can attend schools that will educate them.

Hispanics earn less because so many of them are illegal immigrants with few skills who have trouble with English.

The bottom line is that if America was systemically racist Blacks from Africa couldn't earn more than whites.
