Your completely missing the bigger picture and confusing issues. Women showing a lot of skin is sexual objectification within itself. If a man wearing a low v shirt showing chest hair is trying to incite you to into a business deal, you are distracted by his sexual objectification and you will judge his character. Men wear shirts and pants professionally. Conservative, non sexual. Women tend to wear sexy clothing even at work...my point is its not a result of media that men see women as sex objects when showing off body parts, its the women sexually displaying themselves. Which is even worst considering how male sexual psychology is visually driven.
On salary differences, its well known that specialized knowledge and skills pays more since companies are seeking out the rare talent. Male psychology is more geared to work on a single project using our "one track mindset". Generally speaking women tend to multitask, never fully given their attention to a single problem to find the best long term solution but rather a quick fix to move on to the next task. Its not always true, but collectively male and female psychology is different. In capitalism, where not only productivity matters but also experience and skill-sets, male psychology naturally tends to fit jobs that offer better salaries. It's not by design, is economics: supply and demand.
