The fact that toting it all up results in an overall income disparity does not mean they are equating crab fishermen with people working the counter at Starbucks.
Err yes it does.
Unless the gender distribution of a given trade is even, that trade will weigh the average towards one side of the graph or the other. Crab fishermen are predominantly male as such fluctuations in fishing income effect the male income average more than the female. Likewise if Starbucks employees are predominantly female changes in Starbucks wages will naturally effect the female average more than the male. If (for the sake of argument) there are 2 male welders for every female welder an increase in welder's wages will have twice the effect on male average income that it does on female average income.
Seriously, this is high-school level algebra, it should be obvious and intuitive.
