>We, socially, consider 'women's work' to be less valuable then men.

I definitely agree with this when we're talking about teachers, nurses, librarians, etc. but I don't think web/product/UX designer is a particularly gendered role. It just looks that way because there are so few working women programmers (in comparison to their solid majority of the population) and the sex ratio for designers is more even.

We consider designers to be less valuable than programmers because there are 5 times as many of them than there are programmers.

Of course designers do something that you can't, and if programmers were common, the designers would be calling the shots. Architects do something you can't, too, and they make a lot less than you do - because there's more of them than we need.
