WHen was this? I watched this show for damn near 10 years, and never saw that.
I think it was mostly during the first-term Obama years when the Tea Party critique of "big government" was at its height.
Here is one old New Rules segment where he points out the benefits of a more socialist approach, points out how it works well in other countries, and rails against the hypocrisy of people who fearmonger about socialism but benefit from it and love it.
Here is another clip of Maher defending socialism and arguing that there are many things that should not be run for profit:
Maher has always had his blind spots (Islamophobia, the I/P issue, etc.) but there was a period where I thought he was more on point than not. I think he was actually an important voice regarding certain issues (and not just weed). But for the last 5-6 years at least, he's gone in a different direction (as I said in an earlier post, I think the starting point was when students protested his commencement speech, and since then PC liberals have been his biggest targets). It's gotten to the point where I don't watch his show anymore.
