Poor people can’t comment because they’re poor. It’s the survivorship bias problem. People who are currently poor probably can’t comment on HN (or have no idea what it is), so what you see, overwhelmingly, is people who were able to escape poverty. This can lead some people to believe that it’s easier than it is to get out of poverty. And since this is an article about true, abject poverty, “I pulled myself up by my bootstraps with my tech skills” doesn’t really help anyone learn anything.
