For one thing, some artists who are unknown to public until they have been dead for many years, may struggle for a living all his life and cannot concentrate his energies on art creation for lack of necessary financial support. We can see that clearly through the life of Van Gogh, now considered as a talented painter. But, when he was alive, he sold only one paint, and in the end, he took his own life at the age of 37. Absolutely, it is a tragic damage to art circles. For another, if there was no support for arts, it could be imagined easily that artists would raise the price of tickets for concert and exhibition, in order to gain adequate profit. Obviously, it would be not beneficial to the diffusion of arts and the improvement of demotic artistic accomplishments. .
Taking accounts of the above things, government should supply necessary economical support to arts. However, governmental action must be based on the respect to the inherent law of artistic development instead of for some utilitarian political purpose. Otherwise, it would violate artistic integrity which is composed of variety and freedom which can also be defined as independence.
If government provided discriminatorily funding for partial aspects of arts which maybe is suited to governmental demand. It would be bound to lead to such results that only a few of aspects of arts which get enough funding from government could develop rapidly, and others aspects which are ignored or even restrained by government would make slow or even no progress. Obviously, it is a severe detriment to artistic variety. In addition, after all it is government that predominates funding and power. Out of the awesomeness to the authority or the purpose for enough patronage, some artists will choose to cater to the high and mighty. As a result, they will forfeit the freedom in artistic creation and only consider which kind of works will be admired by these in power.
If artistic variety and freedom had all been devastated by government action, then, the arts would become only a rigid political tool of government instead of the spontaneous expression of artistic emotion. It would be a pity for mankind. So, Government should offer essential funding to every aspect of arts and then leave it alone.
