Kohli and Anushka become NRIs - what's your take?

Everyone has much to say about this. Of course the age old 'brain drain' type argument is there but because it's a cricketer, people seem genuinely hurt that their Indian hero is doing this, leaving their beloved motherland.

If Kohli and Anushka being as rich as they are and as privileged as they are are moving abroad, shouldn't we be thinking deeper about why rather than just getting angry or hurt?

Why do you think super rich and famous people also move abroad? What is their motivation?
