India for "Foreigners"

In India, what is a „Foreigner“? Does this term simply mean foreigner, or is there more behind it?
Why are old people more respected in India than in the West?
What about corruption in Indian society?
Why are the speakers always so unbearably loud at events of all kinds in India?
What about child labor in India, especially in 2017?
These and many other questions have been masked, of Indians about Indians, by the author, (who has been traveling throughout India for 14 years,) and whose answers have been included in this little book ... hoping to build bridges of understanding, where they are missing.
It is understood that these observations are based only on the personal experiences of the author and the personal knowledge of several Indian friends, therefore, it is understood that these facts cannot be described as universally true.
