Required reading for discussing any of this is "Is there anything good about men"? According to this, there's a preference (genetic and societal) to condition men to take risks, and that risk skews the distribution outward, with more failures and successes. One of the main punchlines is that comparing means is useless. Men just have way more outliers in both directions, and grades (maximum-capped) will tend to be lower on average, while income (no maximum cap) will tend to be higher on average.
