Yes, with modern systemic hypercapitalism and citizen powerlessness in the US, corporate leadership is paid too much. That's one part of the story. You forgot every other part of the story.

Investors and venture capitalists are also paid too much, and workers are paid too little. Those are other important parts of the story.

But the most important part of the story you forgot for your particular example of explanations to a single mother buying diapers about why she should care about the Gini coefficient is the complete absence of cash benefits in the US for being parents. Luxembourg, Belgium, Austria, Germany, Canada, Ireland, Sweden, Finland, Denmark, Norway, Netherlands, and France ALL pay THOUSANDS in cash each year to single mothers for being single mothers in addition to the free child care and the huge period of paid time off they receive if they choose to raise their kids in their own home without using the free child care.

Do you believe the single mothers in those civilized places are upset when they see American mothers paying a few pennies less for diapers in Walmart than they pay for local products when their local governments support them as parents instead of abandoning them?

Idiot.

If you don't even know what systemic change is then don't waste pixels arguing against it.
