As I have grown older and (maybe) a little wiser. I realise that these rosy macro numbers matter little when it comes to your personal quality of life and future.
Why would rational people take a loan on their life's assets for a remote chance in a foreign land? Simple, because they think it's worth the risk since the rewards here are so abysmal.
Take your chart, out of the millions of graduates we have the highest percentage with the least employable skills. Those who are good and graduate from IITs leave for the west. Leave this, all this VC money and FDI have benefited very few and those few (around a lakh or so according to official stats) are the ones brave enough to file an ITR with more than 1 Cr. income.
Aside from this we as a country have completely forsaken two key areas for quick service cash. One being manufacturing and the other being research. Manufacturing deserves its own post but India just sucks at quality research. I'm friends with some of the best and brightest botany researchers in India who have tried for a decade to secure funding and livelihood by venturing into remote forests for their research only to give up and go to the EU simply because they have a future there.
I don't mean to downplay your post but please take a look outside and think from the perspective of ones leaving. I've been promised better roads, sanitation, and education for the last ten years of my working life and I'm tired of waiting.
Lastly, our current state and future is a reflection of our leaders. I'll get downvoted to oblivion for this but our leaders are simply not Empire builders, they are term to term politicians.
