Fixed fees do not create incentives for contractors to do the best job that they can do. The braod majority of government contracts used fixed fee awards. This wastes government funds! The U.S. should switch to using performance based fees, and remove the use of fixed fees under all circumstances, except special cases as listed under a FAR update.
All galleries, museums and historic soceities including monuments should charge a minimum entry fee (not labeled as a tax nor charging children less than the age of 5). The costs of security and building maintenance is not cheap. A minimum fee would help bring income in to reduce costs and debt.
