I always thought that culture was what we as a society value, and the expression thereof, materially, spiritually and aesthetically. That would include both inherited and aquired values. When the obsession with the self negates any remaining culture. We attend an orchestra performance as an audience that has values in common, at least with others who attend, as a social social function. It is akin to those who cannot afford the time to become informed as to the issues in order to express their ballot and participate in the democratic process.
Democracy is just too expensive.
Except for those whose admission is spaid for by the public purse, and when the performance subsidised, provided it conformes to the requirements of the ruling elite. Where then can we find the expression of the culture of which the masses are the owners. The culture of the poor is bread, that of the wealthy is circuses. You are giving me opinion. Yes, you mention an economist.
