In a sense, capitalism always discriminates against people on the fringe of society. Demand creates supply, and where there is less demand for a product, there will be less supply. Most men wear either suits, or plain jeans and t-shirts, so most of men's fashion revolves around those limited choices. Most women are shorter than men and have smaller feet and narrow shoulders, so clothing for girls with more masculine frames tends to be hard to find. There are enough of us to create demand for some products designed for trans men and women (HRT, surgeries, etc.) but we'll never occupy more than a tiny niche of the market because of how few of us there are.
I suppose one could imagine an economy where, instead of allowing demand to dictate supply, the needs of every citizen would be considered and addressed with an equal share of care and attention. Men would have access to frillier clothes, lingerie, and other, less mainstream styles designed to fit their bodies; more time and energy would be devoted to researching and developing products and services for trans people. Such products would not be produced or distributed in the same manner as products demanded by the majority of society, but would instead be available per request, to be produced and delivered to those who need them. This system would be similar to our current capitalist model; the difference is that, in our "fair capitalist" economy, fringe groups would enjoy the same wide range of options as those at the center of society. Imagine a world where there are more types and styles of prosthetic limbs than there are amputees who need them.
Keep in mind that these additional products would not be produced before being ordered; they would instead be created to order, made only at the fringe consumer's request. We would have a surplus of
designs for fringe products, not warehouses full of unused merchandise. Fifty years ago, such a system would have been infeasible, but with modern 3D printing, we can create individual items on demand provided we have a model to build them from.
Mostly, I'm just imagining how easy it would be to find size 12.5 women's shoes in a style I like under that kind of system.

I'd just have to wait an extra day or three for my shoes to be delivered.
Sorry if my rant sounds confusing; I just woke up and may have gotten a little carried away.
