Can anything be done about the degeneration of the patron?

In a democratic republic how can we patronize the best art and culture when our patrons tend to be the depraved swindlers and vulgar loudmouths of Hollywood and New York? It leads to thinking about the temptation of aristocracies, which supposedly patronize the very best creative people.

We have witnessed the downfall of art and culture promoted by the Big Media (and postmodern academic frauds), patronized by predatory global corporations who control the culture. Can anything be done about the degeneration of the patron if one wants to work within the system we have?

As usual I see the separation of ethnic cultures within ethnopluralism as the best chance of developing patrons with better taste. Then the plebeian-bourgeoisie newly rich will not have national and imperial power over all cultures.

With ethnopluralism distinctive cultures will have a longer-term chance to rise in their own regions, protected by federalism. This could be accommodated by the separation of powers and states in the U. S. Constitution. Some states could promote aristocratic patrons within a democratic republic, and even the loudmouths could have their own culture.
