I’m not the original person you were speaking to but this is a good example of systemic issues. You don’t need individuals to be racist or sexist or conspire to do bad things if there’s a systemic trend that people in powerful positions are a homogeneous class with their own relatively aligned interests and social circles.

Billionaires don’t know poor people, billionaires are usually white men, billionaires have similar self interest. Billionaires wield a huge amount of power. BOOM. systemic racism and sexism without requiring everyone to scheme and coordinate.

This is why liberals fixate on gender and race representation in higher positions, and this is why I and other leftists just want to dismantle unbalanced power structures that give billionaires everything and allow them to exist.
