Whether or not there is shame in getting help for your depression is cultural. Saying so on a hackernews post doesn't change the reality on the ground for any potential viewer in, for example, Japan or China.

The health care situation in your country matters a lot too. Plenty of people are depressed and too poor to afford treatment.

Getting help may mean adjusting location to a less shameful community. With Internet communities and now the beginnings of Internet medical care, this might not even require geographic changes.

Are you suggesting people struggling with major depression move to a different country?

It was a little front-loaded, but the phrase "this might not even require geographic changes." at the end of his reply implies that it's less "move to a better country" and more "stop hanging around with people who damage your mental health and/or shame you for seeking help". This is very good advice, and following it in the past probably saved my life.
