The guy has to be a liberal plant with these answers.
Women’s pay gaps are essentially nonexistent wen you factor in the rational reasons - starting salaries/wage differences, varying experience levels, time away from the company not working, so therefore no pay raises or promotions during these times, different jobs are paid differently, still some higher earning jobs most women don’t go into because THEY DO NOT WANT TO.
So many gals I knew didnt want to go into engineering because they didt want to work that hard. Dont know how many times I heard that. Journalism, general business school, teachers.
I'm in agreement with your reasons. And I have other reasons. I believe in equal pay for equal work, but not equal pay for women versus men. It depends on the situation.
In my experience, many women underperform versus men. They'll get male co-workers to do the heavy lifting. An exception is where upper body strength and dirty work is not a factor, and then your reasons kick in. Women can and do outperform men if it's a desk job. Otherwise, they don't want to get their nails dirty and simply can't do the heavy lifting, but they demand equal pay for underperforming versus their male co-workers. I've worked with some excellent female engineers who do good work. But I've also worked with some female workers who simply are not cut out for the work, but bosses don't hold them to the same standards as men.
