Successful films and TV programs make large amounts of money, and so do the performers who appear in them. A few big shows can make a rock musician a millionaire(百万富翁) in a very short time. High art, however, has serious financial(财政的) problems. It costs more to put on an opera(歌剧)concert, or ballet(芭蕾) than the sale of tickets can bring in. Men and women interested in high art are always being asked to give money to make future performance possible. Small government subsidies(津贴) have also helped to support the arts in the last few years.
