thank you so much for sharing your thoughts. I was watching the movie just yesterday and had pretty much the same discussion with one of my friends. even if Thanos' perceived problem were real, killing off half the population wouldn't be a solution. instead he should have looked for a way to encourage distributive justice of resources. (also, the universe is not finite, as he claimed, but it is expanding; scientific inaccuracies are a whole different topic, though)
also, as someone with little to no knowledge about economic theories, I found the video to be very insightful. :) cheers!
