There are some parts that are legitimate issues to be concerned with, but the show places a huge emphasis on overpopulation specifically and not very much focus by comparison on matters such as resource allocation, economic systems, shit like that.

So you get a cabal of rich capitalists that get to essentially unchallenged* present the issue as one of all of humanity at once, and not one that they are directly and constantly perpetrators of. As with the other comment, is there a world where season 3 would critique this? Maybe, but that doesnt seem likely given that the provocative nature of the show is the supposed moral dilemma of population culling vs humanity facing extinction.

*Unchallenged in that the claims they present are not challenged on a factual basis, nor are the protagonists able to present any opposition in terms of what can be done about the issues but only on matters of morality, and the only protagonist who even has proper knowledge of the same issues is entirely convinced of the antagonists worldview and plan, while those that continue opposing the antagonists legitimately do not have knowledge of the issues.
