Downsize Government & Raise Revenue: Sell Government Owned Assets

One way government could easily raise revenue is to sell government owned assets. Strange that I don't here either party talking about this. Here is a quote from CATO's Downsizing Government website.

"At the end of fiscal year 2007, the federal government held $1.2 trillion in buildings and equipment, $277 billion in inventory, $919 billion in land, and $392 billion in mineral rights. The federal government owns about one-fourth of the land in the United States."

At the same time we could also privatize roads, air traffic control, airports, and anything else that doesn't impose negative externalities.
