3-3 the value of art programme

As for setting up the museums, theatre and so on, as far I am concerned, it is essential for society the progress of society in the long run. For one thing, one of the differences between human beings and animals is that, except in addition to food, we demand spiritual satiation/satisfaction which it is such as art can that could provide to a certain degree. For the other thing, varying from/contrasted to/differing from those facilities I have mentioned before, something like an art exhibition is one of the contributing factors to national economy, for it can be lucrative. In like manner, since not everyone has the ability to appreciate arts, excessive importance/significance attached to the works of art is a disadvantage/has its own feet of clay (not a good idiom in this context).

overuse of 'linking phrases', and filler phrases - underlined; I can see you are trying out phrases for your own purposes or for the attention of an examiner.  However I am unsure what you actually said here.
