The sentiment is not wrong, I believe that is just your opinion. I believe the opposite is true. Art and culture are and always has been personal, religious and state matters. Fortunately, there is nothing in the US Constitution, nor in any state constitutions as far as I know, that bans government from participating in the Arts (providing funding, maintain galleries, etc.). Art belongs in the schools, public spaces and in all parts of our lives. I am glad some of my tax money goes to the arts.
In the recent past, it has been the conservative factions in Congress that have threatened to cut art funding when they see it spent on art they do not approve of...art that challenges how culture is defined, art that challenges the status quo, art that challenges religious concepts. This flies 180 degrees from what you stated. Art belongs to everyone, and should not be just defined by the market or by Congress.
