There are many improvements that are coming, albeit slowly.

LOL! I dint know that only India was facing these problems. When I ask outsiders about their country, why do they keep cribbing about their country too facing poverty, crime, corruption and so on. If we check, every country does have certain minus points as compared to plus points. No country is perfect in that respect.
Regarding Akhand Bharat: I don't support this unison as each country is happy being an independent country. There would be many problems if we think about their unity and calling them just Bharat.
