“There is a big academic debate on social class as opposed to income. There are sociologists who argue that social class is in decline in regard to lifestyle, consumption factors and politics as coherent, meaningful groups.” One study finds that “lumping people into big groups like the ‘working’ or ‘middle’ class on the basis of their incomes ultimately had little to do with what they bought, what they watched or whom they voted for. Rather, cultural and political similarities are more likely to be found among people who are in the same profession or do the same type of work, reinforced first by educational training and then by work experiences.”
