I read somewhere that they did a study and found kpop drama to be a hit mainly among low income poorly educated Chinese communities.
From personal experience this does seem to be the case. The majority of the Chinese prostitutes I've met watched, talked about and obsessed over kpop soaps. While most of the highly educated men I know sought company from prostitutes, and rarely watched any TV.
The highly educated women I know, hrmmm don't know many of these.
I personally don't consider myself above anyone else, but I've not been drawn to anything that doesn't involve aliens and spaceships ever since I got my first legosets at 3.
I have personally watched honeyboo boo and duck dynasty which are considered lowbrow entertainment among american shows.. I watch them because their way of life with all the fish and fried foods are a complete novelty to me.. I've not lived in the south.. and I think it'd be nice to move there when I'm about to die. I'll just go there and eat sugar and fats until I die of a stroke..
Overall.. I believe the boy+girl soaps (of any country) exploit the same super power fantasy as other tv shows..
The characters are always pretty of course, they go from highlight to highlight in the life shown to you, they have jobs, but you don't see them working.
That is more or less a super power fantasy.. living highlights without having to work..
If we look at say.. Superman.. his power and intellect if listed on nasdaq would be above all of the resources and wealth of humanity combined.. and when we watch him do his thing, it's all play and no work..
you might argue, well superman is saving people, that's his job.. NOT REALLY.. superman has no reason to save people.. it just happens to be something he wants to do, therefore to HIM it's an optional excursion, therefore akin to entertainment..
So.. in many ways all television fans are seeking the same enjoyment. They want to feel the -something-for-nothing-... an impossible payoff... a believable winning of the lottery...
also.. to clarify, I am not saying anyone who watches kpop drama is a chinese prostitute, I merely used the comparison between them and chinese business men, because those two groups have the highest disparity in education among the people I've dealt with.
