I think people often mix up capitalism with market-based economies. The former describes social relations while the former describes how commodities are distributed.
I’m personally not a fan of either. A planned economy geared toward people’s need, with the withering away of socio-ecomic classes (no more worker and capitalist distriction) just makes better sense to me.
What country/region are you in?
In the North America, I’d recommend Novelkeys, Omnitype, Mekibo, Cannonkeys and spacecables (spaceholdings) for GMK sets
A better approach is to keep your eyes out on Geekhack. The majority of keyboards and keycaps go through an interest check there, and then the designer announces all regional vendors/prices prior to a groupbuy.
