I have never been to India but I live in Thailand. India sounds like a hot steaming mess, but then many of these countries are. Thailand is extremely corrupt and ruled by a few oligarch families; democracy is bought outright.
But what they have done is recognized the opportunity for foreign investment; the laws to start a business in Thailand are basically impossible for a foreigner - except! - they made new laws under a Board of Investment that can get around all that and make it super easy. If you have cash, you can build a factory here under very favorable terms.
Perhaps the difference is that in Thailand the entrenched powers have a vital interest in attracting foreign investment where in India they dont?
Aside from laws the cultural norms may also be a problem. Laws are really not enforced here but the culture is such that hygiene is excellent pretty much everywhere. Not an issue.
Does Thailand even have an official government today? I also respectfully submit that it is very different from India. But I may be wrong on that.
It is fascinating to me how a functional legal system is like 'software' for a good market economy. I hear in the C.I.S. one can show up to one's business and find the locks have been changed and new tough young men are around to explain you no longer own it.
