Posting this type of content itself is not the issue, but rather it comes down to the sort of commentary or questions that the OP (in this case, yourself) is contributing with it.
If you were wanting to ask for clarification as to whether the claims in the video were true, sensible or logical then that is one thing -- i.e.: challenging the premise and claims to begin with.
But you were asking what could "explain it", meaning that you believed that the claims and premise in the video made were reasonable.
Perhaps you did not intend it to be bait and did genuinely believe that the claims made in the video were reasonable, but in that case it just means there's a bit more to learn and to be vigilant about, and you're going to continue getting this sort of response.
What I believe to be reasonable is the claim that China shows slower night-light growth than GDP growth, this isn't really disputed, there are quite a few more scientific articles investigating this, such as the one referenced in here:
. It makes very little sense for them to lie about something like this that can be proven/disproven with readily available satellite data.
Does this mean that night-lights are a good proxy for measuring GDP? Not necessarily, and I never "accepted this premise" in my original post. There are plenty of measurement issues, but why China, specifically, shows slower night-light growth than GDP growth is worth discussing. It might be a measurement issue whereby night-light growth in megalopolises is not fully captured, or simply that Chinese growth took place in areas unrelated to night-lights. This would answer my question of "what could explain the slow night-light growth?"
To be fair, I could have been more specific and said "what could explain the slow
perceived night-light growth", to more clearly leave open the option of internal validity issues.
