Sadly, we as a society have become reliant on Chinese exports, and we cannot actually change that as everyday people because Chinese made components are in most electrical household devices and appliances. This will only shift when there is governmental level pressure on a country to make changes necessary, which does happen, just not to extent that it needs to.
I find going from a ladder DAC to an RME a little bizarre though, there will be ladder DAC's that are 'assembled' in other countries other than China - AQUA for one, your RME dac has Chinese components, so while it may not be assembled in China, a lot of what is inside is, therefore it's no different really than buying a Chinese brand. At least with a Chinese brand, you are supporting a small business enterprise instead of just supporting the poor wage/high hours factories that make the components.
Are you claiming Denafrips have human rights violations in their company? Also, the Chinese are notoriously hard 'bargainers', that's just the cultural norm, so I am not sure what relevance this is? Have you got a link to this info from your OCD guy?
You have to ask yourself if you or any of your friends, family use low price clothing shops such as Matalan, Asos, New Look, Burtons etc because the fast fashion / sweatshop industry is a far bigger problem than Chinese electrical component factories, but people want a shirt for a tenner, and a new one every few months rather than paying £50 for a shirt from an ethical company and it lasting years.
