This Hate for india scares me

I have been following this and indiateenagers subreddit for a while now and the general amount of children who want to leave it is soo much it actually scares me a bit, in my village back in uttarakhand their is absolutely no one under the age on 30 actually living their it's either their old parents or their wives and children. I am afraid that the brain drain we talk about, its only just begun. Soon india will lack actual skilled young people. Also one thing that baffles me is the feeling of helplessness amongst the children here. We all are legit fighting a government body(NTA) and pushing them on the backfoot, who is to say that us, the future of this country can't change it for the better? Why are the students more focused on getting to america or canada or Australia instead of making india a better one? (You can call me extremely optimistic or too naive and dumb thats ur choice ofc)
