This idea would also help us avoid future oil spills by becoming less dependent on foreign oil .At the end of the Industrial Revolution our government entered the White Collar Era. We have grown up during the Information Age which morphed into the Digital Age that we are in right now. We seemed to have forgotten the basic concept that made the Industrial Revolution one of the most important events in human history. "Interchangeable parts." Sure our software and hardware take advantage of this concept, but what about our brick and mortar, our great investment in land, buildings, and interior space. In order to achieve mass production and manufacture a profitable product, Henry Ford and others made capital investments in factories with assembly lines. The industrial revolution would not have been successful if they only used these expensive investments 8 hours a day for five days a week. They greatly reduced their ongoing overhead by operating three shifts a day and some shifts on weekends. The Federal government pays for almost 2 billion square feet of office space. Most white collar workers work an 8 hour shift each day. The office space is available 168 hours per week but it used for only 45 hours a week. These expensive facilities sit unused 60 to 70% of the time during the week. 30% EFFICIENCY IS UNACCEPTABLE in today's economic and ecological environment. I suggest that we schedule white collar work for 2 different 8 hour shifts each day instead of one. At 40 per square foot, our government could save $40 billion per year by leasing or owning 1 billion square feet instead of 2 billion. There would also be hundreds of millions of dollars saved since we would need less computers, supplies, and office equipment. This is possible since most government work is electronic as evidenced by the Telework Improvements Act which has now passed the House and the Senate. If adopted by government and private industry we would: Save the government close to a half trillion dollars in the next 10 years; Reduce white-collar overhead costs by 50%; Reduce carbon footprint of office space by 50%; reduce budget deficits for most state governments; reduce our dependence on foreign oil; make workers competitive in the global economy; improve profits for all businesses; increase tax receipts for state/fed governments; allow businesses to hire more employees & lower prices. If applied to healthcare industry, we could use current facilities to serve the uninsured.
