Democracy with 1 billion people?
Challenging. Just look at India and it's problems.
It could actually be argued that India has no business being a one country, should have been a union of countries a la the EU.
The two party system creates an us vs them mentality where both are equally bad on most things but there is no real choice for the voters.
It’s the least bad system we have.
Perhaps it's the cleverest (in the negative connotation), most sociopathic, and those who've inherited it who are the oligarchs.
