Both Jaemyung and Minseok... once they reached high positions... have they learned a new language?

Before they took their positions, they were so articulate and smart...
But now that they're in power, I can't understand a word they say...
Jaemyung is being so ambiguous, making it unclear whether he's targeting a pig or a Buddha...
And Minseok... he's saying incomprehensible things about "creative relationships"...
When they get into power, I can't understand what these kids are saying...
I can't tell if it's my fault or their fault....
But... they were perfectly easy to understand before they took their positions...
Therefore, wouldn't it be more rational to hypothesize that it's not my level of understanding, but rather that the people speaking are failing to speak clearly?
