The issue arises when the first significant political roadblock occurs, which is literally the American Great Depression. It's frustrating how much the author glosses over the intricacies of this major event. I don't excuse that lack of depth just because it's a comedy story. Any author should not include a significant plot point if they can't think of how to carry it over several chapters -- especially if it's the pivotal first plot point that's meant to hook you in!

Aside from that, the other issue is just how the author manages the politics. The author equates the political left with communism. While this is certainly the case in East Asian countries (sans Taiwan), this is not the case in America. This was also during the time when the American political right and left were swapping positions on many issues. It feels frustrating seeing such inaccurate representation of the American political sphere and lack of nuance especially with such a well-documented event, and with how they are going to be understood in today's context. It also just stands out in what is meant to be a comedy story as a stroke of seriousness.

It's possible that the author's own biases influenced them representing the political left in such a negative light. As aforementioned, Korea is extremely conservative even within the subcontinent (progressives are less than 1% of votes). That would explain the communist angle. There are also thousands of other possible factors, so who knows.
