Newsweek has a great story on the thriving and growing democratic, free-market powerhouse that is today's India.
Good quote: "The marketing slogans wouldn't work if there were no substance behind them. Over the past 15 years, India has been the second fastest-growing country in the world—after China—averaging above 6 percent growth per year. Growth accelerated to 7.5 percent last year and will probably hold at the same pace this year. Many observers believe that India could well expand at this higher rate for the next decade."
India's roaring success over the last generation, through some times of troubling unrest (which, by the way, is something all democracies go through), stands as a testament to both the power of free markets and to the value of democracy. They're also, frankly, a rather "in your face" offense in the eyes of those who make certain questionable claims, namely:
1) "Overpopulation" causes poverty and starvation.
2) Countries can only hold together if they share a unified language and ethnic culture.
3) Countries formed artificially by an external power cannot be stable or successful.
4) Muslims are an impediment to pluralistic liberal democracy.
India was formed into one nation by the British. Although Pakistan, Bangladesh, and Sri Lanka all split off after India was granted independence more than half a century ago, the largest section of this vast nation territory remained as part of the Republic of India. After experimenting in socialism and a long dependence on international aide just to stay alive, since embracing free markets and strengthening and liberalizing their political institutions, they've been rewarded over the last generation by explosive growth, improved standards of living, and greater political and social stability. All this despite the fact that it:
1) Has a greater population density than China's, and may soon have more people than China.
2) Has literally hundreds of languages spoken within its borders, with no less than sixteen officially recognized tongues: English, Hindi, Bengali, Telugu, Marathi, Tamil, Urdu, Gujarati, Malayalam, Kannada, Oriya, Punjabi, Assamese, Kashmiri, Sindhi, and Sanskrit. That's not counting many unofficial but widely spoken languages, such as Hindustani.
3) As noted, India wasn't a single country at all before the British, with their trade interests in the region, formed a national government there. And while some parts of it chose to go their own way after the exit of British rulers (see above), the largest segment remained part of India and has been wildly successful. Indeed, it's been more successful than any of those nations that split from it.
4) Muslims are a much bigger percentage of the population there than they are in any European country where muslims are supposedly destroying democracy.
It is entirely plausible that in 50 years they'll be the largest and most economically powerful country on the planet. Which wouldn't be a bad thing at all, since one country's success is not another's downfall.
