Hard Working Families - What are they?

[sweetjessicajane]

The politicians keep harping on about "hard working families" and how they want to help them.

Firstly what is a hard working family?

Secondly how do politicians know what "hard working families" want?

Thirdly is working only valid when it is paid work?

I think we can assume that 'hard working families' does not necessarily imply that the work is hard work.
