People who justify enforcing a social policy on the grounds that it is 'good for society' are usually attempting to force others in society to subsidize their chosen lifestyle.
Hence the 1988 statement by Margret Thatcher 'There is no such thing as society. There are individuals and there are families.'
For example, a social worker who argues for more more money for social welfare is actually arguing for more subsidies for their profession, so they can have the opportunity to further their careers and raise their income.
