Him: theoretically, sure!

Me: Then that's communism, btw :) Have a look at the UN figures for Soviet Russia and you will see an economic graph that never went down despite being the most sanctioned country in the world. Cuba... produces the best doctors in the world, has no starvation, the best electoral system in the world, and the highest life expectancy in Latin America. And also notice how no Communist country has ever produced terrorists that have pulled buildings or killed anyone!

Him: But you have to admit that Communism is about making everyone poor!

Me: Let me ask you. Do you want to be rich?

Him: Yes.

Me: ... and the person next to you?

Him: Sure that would be great!

Me: and perhaps everyone in this aircraft as well?

Him: So Communism is viewed as a good thing?

Me: Yeah. At least, there is no antagonistic anti communism like you have in the west.

Him: All Soviet Bloc countries in Europe are poor. How do you guys still follow Communism after communism did that?

Me: Communism didn't do that. The Eastern bloc countries turned poor en masse after they abandoned Socialism btw.

Him: So what do they do? Revolution?

Me: No. India's communist parties follow the electoral line because they still can occasionally gain power peacefully. Though there are many hardline Maoists that believe in Armed struggle. The CPs also have trade unions, they do a lot of societal transformations, etc wherever they are in power.
