There is social market economy which can be cosidered to operate within a capitalist framework to some extent, but also to operate within a socialist framework to some extent https://en.wikipedia.org/wiki/Social_market_economy. So it is worth to also think about it as continuous phenomena and not as binaries. But I agree with you: "I'm a devout capitalist. I believe very deeply in contributing to society" made me think selfdeception, too.
