Socio-economic groups

Overall I disagree with the idea of catogorising people due to their income and job title. It is almost de-humanising to put certain people at a higher class than other people ( e.g class A compared to E). I feel that everyone should be at an equal level. Although the use of Socio-economic groups is exceedingly useful when defining your type of audience when creating a music magazine as you can easily narrow it down and choose which Socio-economic class is best suited for your magazine&type of genre.
