Boot camp doesn't do anything lol. Spending a few weeks playing Korean soloqueue isn't going to vastly improve your play.

To beat Korea, the west would basically have to completely revamp their work environment. Top Korean players play at least 12 hours a day, if not more. They either scrim, or play soloqueue on and on, only stopping to eat or sleep. Teams in the west would have to also follow these types of schedules. In a few years, they might have a chance of catching up.

But honestly that's never going to happen. There's little reason to pursue league now as a professional career unless you really love the game. It has little job security and basically puts your life on hold for a couple of years as you sit in a house accumulating zero skills for when you finally retire and get a job. Right now the best retirement plan is trying to make it big by streaming, but we obviously know how that ended up for the vast majority of former pros. Team managers telling players to basically play league for such a pitiful payout would never work out.

This isn't like the NBA where you earn tens of millions and get massive endorsement checks and your own brand of sneakers if you make it big. Not to mention massive fame and a shit ton of love from millions of fans across the country. The biggest player in the West, Bjergsen, probably isn't even worth 10 million right now, which is a fraction of a superstar basketball player's salary (not even counting endorsements or other stuff) for a single year. And I don't think NBA basketball players play 12 hours of basketball a day, every fucking day. Why should Bjergsen be forced to dedicate more time to League than a basketball player, who not only has an exponentially higher pay, but also most likely a longer career span? It's fucking ridiculous to expect that.
