art is useful outside career field
I do not agree, art was not practised by earlier generations of humans as a "career", it was practised to express feelings and opinions as well as represent and write history. Fro 18-20 century art and music was very popular, some artists mastered art so well visitors would cry because it was vivid or expressed feelings of sadness or betrayal.
