You'll learn why if you read this voluminous explanation. But it IS the responsibility of the government because it is the will of the taxpayers and voters; the government works FOR US and it is what we DEMAND how our tax dollars be used and not wasted on frivolous endeavors to pay off political cronies that do not serve a useful purpose for society.
WHY is it the responsibility of the government to HELP with a paltry, tiny, insignificant funding amount in the overall budget, far less than given to big business as “seed money” and certainly less than giving away billions to rich oil companies to further boost their obscene profits?
First, the arts are a part of our culture, a part of what any and all civilized nations share in common, a part of history and people as a nation or society. It TELLS what a “people” are about, in illustrated mediums (paintings, for example, or illustrations on posters, billboards, etc), written mediums (poetry, literature in fiction/historical, song-writing, etc), visual and performing arts (dance, stage and theater acting, film acting), etc. It enriches people, allows for personal creativity and creative outlets. It entertains to create soothing or stimulating effects to the masses and, equally important, it causes reactions, emotional and intellectual, to viewing audiences. It continues to stimulate and bring us new talent, too.
Why is it so important that the government help, at the very least, the arts and cultural events? Because it brings in a significant amount more revenue by way of taxes collected and creates more jobs for people that also pay taxes in an incredible diverse areas than if it did not help fund.
You must understand that the arts is responsible in more ways than you can imagine for funding the government. It creates jobs and companies that hire people to earn money to pay rent/mortgages, buy groceries, buy clothes wear and footwear for themselves and family/children and, creates profits for neighboring/local stores, sandwich/lunch shops and street vendors (they also pay taxes and have a slew of personal purchases to make), delivery personnel, office workers, counter personnel, maintenance crews… but, they also provide the talents for magazine writers, editors, photographers, office workers and other personnel (maintenance crew), and for TV programs and/and movie companies that hire actors/actresses with their own office personnel, contract writers, storyline writers, attorneys, artists, carpenters, electricians, special technicians, specialists in other areas, like sets and settings, etc., even maintenance and security personnel that all pay taxes, too, and make personal purchases with their earnings and they pay taxes.
People involved in the arts fund over 95% of all arts and cultural events in America, through donations and ticket-buying. That money STAYS in America as long as we continue to have arts and cultural events, and we enrich our newer generations through exposure. Unfortunately, dull-minded people are incapable of understanding the impact and immense significance of arts and culture, or its vital importance and role to society.
