"Best" art in history is a relic of past powerful people's taste and ambitions. And of the preservation of it (still today, there are fools that willingly destroy/erase remnants of art or culture).

The difference is that today, civil servants/"democratic" structures/the "free" "market", through intent or fate, are also some of the powerful ones.

The point would be to find a structure of power that allows each and every one to express themselves fruitfully for/to the whole.
