Is there a consensus that cultural, erotic, social capital exists and can be bought with each other and economic capital?
This was the basis of the great British class survey, and
differing dimensions of social mobility can be classified in terms of differing types of capital that contribute to changes in mobility. Cultural capital, a term first coined by French sociologist Pierre Bourdieu distinguishes between the economic and cultural aspects of class. Bourdieu described three types of capital that place a person in a certain social category: economic capital; social capital; and cultural capital. Economic capital includes economic resources such as cash, credit, and other material assets. Social capital includes resources one achieves based on group membership, networks of influence, relationships and support from other people. Cultural capital is any advantage a person has that gives them a higher status in society, such as education, skills, or any other form of knowledge.
On the one hand, I would be reluctant to class someone as bourgeois on the grounds they were good at sex, e.g.. On the other, it does seem reasonably true. An easy solution is yes, but your "class" is determined by economic capital.
