I guess my code of ethics is independent of whether I "like" someone? It seems a little immature to be unable to acknowledge that someone was done wrong just because you don't like them for some reason. It's even more bizarre to assume that every investor in a taxi medallion must share the same perspective on the ethics of the industry as you do[1]. A lot of people just don't understand the details of the economic system they participate in, and deciding that that condemns them to being undeserving of sympathy is frankly more than a little disgusting. I thought my example of the role homeowners play in our economy would make this a lot clearer: I assume you wouldn't be so quick to "struggle to see what there is to like about" homeowners and decide that they deserve whatever economic injustice is wrought on them.
I can guarantee you there are plenty of things you do, from not worrying too much about the sweatshops you ultimately buy from to being complicit in the torture of millions of animals that many other people would consider unethical. Arguing that people don't deserve empathy if they aren't fully aware and fully conforming to your code of ethics isn't enlightened, it's just the same old gross "I want to be shitty to people I disagree with" under a thin veneer.
[1] FWIW, I agree with your assessment of how the industry works.
