Feeling Left Behind Due to Korean English Education Influence

I still remember the days of "Non-Korean Society" in my hometown when I was around 20 years old and that was a decade ago. No Korean restaurants, no Korean bars, no English academies and no Koreans at all. When one day my father bought a daily newspaper for me to find a job in the ads, because that time I was a fresh graduate, and I saw "Wanted, English Teacher, with or without Experience". From that time on my life started dwindling around English Education and Teaching for Koreans.
10 years ago, the Koreans whom I know that cannot speak English well are now making a living in other countries such as America, Australia, Canada and others. Those who learned to love my country established their own schools either private or just English schools and some came back to their country and probably doing their best in their jobs applying their skills in English.  I had an experience living with a Korean family, working in a small English hagwon in Korea and I am studying right now for my masters degree in English language education. Five years ago when I first came in Korea, children running around me would wonder where I come from but couldn't ask me because they couldn't speak English but nowadays they seem not to care anymore because they've already had a lot of experiences speaking with foreigners. These things or experiences made me strongly feel how important is  English Education in Korea. Everybody in Korea tries their very best to become as fluent as they can in English and they try to do it in a fast period of time. At first, I thought they were crazy but now I think I was a fool. A decade is not that too long but I wonder, what have my country done for our English education? What have I done during those times? What should I do now?
I suddenly felt that my country might continuously disregard these things and I am worried about it.
I need to do something about it.
