Years ago, i watched a telly show on this topic in the states. The format was that in the studio, the audience area was built with space between the rows, so that the MC could walk among the audience. Additionally, it was brightly lighted, so you could see who he was talking to clearly. He started out by saying that he was going to describe a job, and if anyone in the audience had ever held such a job, they should stand up. If he started describing a job that no longer was similar to any job they had ever held, they should sit down. The audience was about 50/50 men/woman.
The first job was one where: "you could be called out at any hour of the day or night. You had no idea when you would return - it could be days or weeks later. You would have no "crew rest" provisions, you might have to wear your clothes the entire time. type of job was emergency maintenance personnel for power, communications facility, radar site. 50 or 60 stood up, they were all male.
The second was a job where: "you were at risk of physical assault at any time. Weapons could be used. Your working hours would generally be 40 to 60 hrs/week, but in an emergency could be longer. Job looking for was: jail guard, corrections officer, fire personnel. About 45 stood up. Only one female.
Third job: You work at a remote location. It requires a helicopter to reach. Once there, you cannot leave until your 3 month 'shift' is over. You work 12 hrs/day, 7 days a week. There are no shopping, recreational, or leisure facilities available. The work area is oily, and vibrates constantly, with some noise. Occasional fires & explosions have damaged or destroyed these work facilities, with some loss of life. The housing provides bunks for the off duty staff - i.e. you share a bunk with another worker. Bath & shower facilities are shared - team shower, etc. Job was: Oil drilling platform worker. 55 respondents, no females.
Fourth job: You work in a secured facility. You are part of the nursing medical staff. The patients cannot leave the facility, and occasionally become violent with little or no warning. They are often on medication which has somewhat unpredictable results.. Occasionally, they must be confined in 'padded rooms'. This often requires a number of nurses and orderlies to accomplish. Job was: Nurse in psychiatric prison hospital. Surprisingly, about 1/4 of the respondents were female - although they were well built young ladies who looked pretty strong.
Now these jobs all have to be done. If you offered only the basic wage, you could not get anyone to do them. Many women (with good reason) would not want them at any price. This is why i feel that you have to carefully consider the work conditions and risks before considering salary. Most peeps don't do this. Cheers.
