Caring about quality is above capitalism or communism. Yes, it can be exploited by any political regime and it is necessary to be aware of this exploitation, but regardless of what is the environment I feel proud of doing a great work.

Good designs, fitting elegant solutions that have positive impact on the people who have to use them are not capitalist. What is capitalist is people just churning out code without considering whether that code is reliable, makes the world a better place etc. Thinking about code quality this way is anti-capitalist, because you say: There are things that matter more than monetary capital or short term gain
