I see a lot of
people are very opinionated, pro or con. I think Vijay Mallya would find it pretty unfair if all of India's problems were pinned on him personally. Anyone would. And in the end we're all responsible for all people on Earth being equal to the degree that basic rights are secured and absolute poverty is eradicated. Mallya, being a man of resources, could of course be seen as more responsible because of his wealth. But who's to say he isn't?
Evaluating things, even only superficially, reveals a complex picture. India has a long tradition being in the very top of mathematical advances and applications. Looking at history, they were very advanced in things like metallurgy and home to some of the very earliest prosperous urban settlements. Contemporary India boasts a middle class of 200 to 300 MILLION people, a number which is steadily growing. I think India can't advance merely by everyone going to farm their fields. (Isn't that pretty much what academics and students in China were forced to do in the "Great Leap Forward" that killed millions?)
India, as is any other country, is entitled to seek (peaceful and ecological, preferrably) advances anywhere they please. The country has a huge talent pool, and if it hasn't yet one in drivers, I hope and trust Mallya recognizes that, too, and invests in lower tier motorsport in his home country too in the hopes of developing one. Meanwhile I can't see a reason to question his motivation or India's role or contribution to F1 merely by supposing things, or assigning them an arbitrary role in the World.
The entirety of F1 will appraise Mallya's personal judgement and team owner capabilities soon enough.
