Infrastructure investment when government is an insurance company

This is important - - The Newest Federal Budget Proposals Cut Infrastructure Spending to the Bone.  From the article:

In the last half-century, the U.S. government has gradually changed from an investment engine to an insurance company. In 1969, direct payments to individuals and investments (education and training, scientific research, and infrastructure) each made up one-third of the federal budget, Ron Brownstein reported. In the last half-century, wars have ended (the defense budget includes investment, too), and infrastructure has languished, while entitlements have grown. Now payments to individuals have doubled their share of the budget to 65 percent. Investments have fallen to 14 percent.
