I am Korean, and what you are saying is a lie created by anti-Korean people in Japan. Do you really think it makes sense for a government experiencing an economic crisis to desperately seek revenue sources and hope to overcome the crisis by funding a cultural industry that hasn't even succeeded yet?

I've always wondered about this, turns out there's a wikipedia entry for it

> To protect the South Korean culture industry, the South Korean Ministry of Culture received a substantial budget increase, allowing for the creation of hundreds of culture industry departments in universities nationwide.[21] It has justified its financial support for Hallyu, estimated to be worth US$83.2 billion in 2012, by linking it to South Korea's export-driven economy.[22]
