and technology drivers, to accommodate population growth and migration, and for other improvements in rural, urban, and low-income areas that the private sector is not currently serving. (6) Although Federal grant programs, along with matching State and local funding, should continue to play a central role in financing infrastructure in the United States, current and foreseeable demands on existing Federal, State, and local budgets exceed the resources to support these programs by a wide margin. ASCE estimates that funds are available for only about half of the infrastructure it currently monitors. Meanwhile, long-term savers, including central banks, pension funds, corporations, sovereign wealth funds, and insurance companies, have a growing interest in infrastructure investment. (7) The establishment of a United States public deposit money bank would provide direct loans and other financing of up to $4,000,000,000,000 for qualifying infrastructure projects. Such funding would be adequate to finance all of the United States identified infrastructure needs, in all parts of the country, according to strategic plans. At the same time, it would return the United States to its most recent golden age when a National Infrastructure Bank was in place (1933–1957), during which time total factor productivity advanced by 3.5 percent per year, the economy grew on average 5.5 percent per year, income inequality fell by one-third, and Federal and State tax receipts rose dramatically. 3.
