Explanation:

Why need Social Security?
India has a very basic social security system catering to a fairly small percentage of the country’s workforce.
Traditionally, Indians relied on their extended families for support in the event of illness or other misfortunes.
However, due to migration, urbanization, and higher social mobility, family bonds are less tight and family units much smaller than they used to be.
So far, neither the state nor private insurance companies have quite stepped up to fill this gap.
