Who it is who really "matters"

Politicians, capitalists, aristocrats.
                                       Useless sods I tell you

All politicians do is play with other people's lives

All capitalists and the businesses they run do is fleece consumers in exchange for shoddy defective poorly-designed products

The real reason we need the arts is because art, literature and music have always been pretty much the only proof the world has ever had that it IS possible to actually accomplish something worthwhile
