Theatre managers are naturally strong in their opposition to the doubling of the tax on theatre tickets, says the New York Evening Post. They maintain that the increase to 20 percent will cause the failure of many productions. But to people familiar with the ways of successful plays, this will not necessarily follow. If a piece 'catches on,' tickets for it immediately go to a premium, and cannot be purchased except by payment of a bonus of 25, 50, and often 100 percent. The successful drama or musical comedy commands full houses no matter what the admission prices. In New York, at any rate, a play is a success and makes 'big money,' or it is a failure and loses 'big money,' no matter how low the price of admission. The levying of additional taxes will not keep people away from a hit, nor would the reduction of these sane tax induce them to the road to an unpopular performance.
