How about supply and demand? I work construction and we hire anyone who is reliable. We have a handful of women subcontractors and trades (unionised painters mainly), nut moat are men. We even hire young people and we can't find enough reliable labour. Generally our  unksilled labour starts  at 18+/hr  which ghoes up to 20+ really quickly if they can show they won't injure themselves or others and can be counted on to reliably show up to work regularly. Skilled labour earns even more. We get next to no women applying and many of the young men that start out don't last more than a month. Why?! Not sure. The work can be physically demanding, but also detailed finishing work. We just can't find young people, men or women, but rarely women. And same wirh most sub trades a men. And a lot of work too boot, more hours than most can work!

My point ia we offer far above min wage because of high demand but low supply of workers! So why should a job with high supply pay the same?!
