CMV: Thanos' plan makes no sense when you take economics and policy into account.

I  have to preface this by saying I realize this isn't a serious topic,  and I understand it's not an important problem to debate (or is it?).

Additionally,  I did not grow up reading Marvel comics, and I have had very little  context on Thanos besides what I saw in the Avengers movies.

Thanos'  plan to eliminate half the universe's population makes no sense to me.  It seems to stem from the idea that the universe is over-populated, that  resources are too scarce to accommodate everyone. He believes that the  snap will prevent economic collapse.  He says: ***“what's happened since then is that The children born have known nothing but full bellies and clear skies. It's a paradise.”***

I am failing to see how this would work:

1.	The  post-snap scene shown in the movie does not show a thriving  civilization. Why wouldn't we see hundreds of worlds being perfectly  happy with how things are now?
2.	If  you cut half the population, I imagine that would initially cause  political chaos, all the jobs needing to be transferred, all the people  making moves because certain people are gone.

But  let's say that passes, and now everything is stable, with just half as  many people. Suddenly, 2x the resources are available, but half the  people are there to use them.

Would this  not lead to a universe-wide baby boom? How would people not want to  start wars with other planets for those unused resources? Am I supposed  to buy the idea that everything will be 2x more readily available and  things will just go on as normal?

3.	I  understand that Thanos saw this strategy work on Gamora's homeworld, but  I don't see how it would have worked in that case either, for the  reasons above. In that sense, I believe Thanos is really falling for a  logical fallacy by thinking his past approach will work anywhere.

Please change my view! I'd love to hear some points that clarify Thanos' plan and hopefully help me make sense of it.

Update: lots of people posting insightful comparisons with the Black Plague, and talking about how Thanos might be the only one who believes his plan. My takeaway remains that his point makes no sense, but he’s just being a space Genghis Khan.

Thanos is also known as "The Mad Titan". He's not exactly sane.

From the Avengers movies, we can see that his kill 50% plan originated from his homeworld, and his plan to save it. That is the driving motivation behind all his actions.

He had a plan, they rejected him, and his homeworld was destroyed.

So, now he wants to repeat his plan, to show and demonstrate that it would work. That is was others fault that his homeworld was destroyed because they didn't listen.

Note : The motivations are different in the comic, and most of this here is speculation.
