The Federal government in the USA is probably the biggest land owner in the USA and effectively controls 28% of the 2.27 billion acres in the country. It clearly has no reason or excuse to keep more than 5% of that land for say national parks, military use and some other minor uses. So why not actually sell that land to private interests and use the money to pay down part of the debt. By my highly through and intensive pen on napkin research and my usual not bothering to check the facts too much I am guessing that at 522,100,000 acres for sale at an average of $1000 an acre or selling off the mineral rights you could raise anything between 1/2 a trillion dollars to 1 1/2 trillion dollars. This money while not eliminating the debt would at least if combined with some serious fiscal tightening could help get to a place where you could at least begin to tackle the debt.
I know it’s not likely to happen and the current administration would sell the land to Americas enemies but when you are broke maybe it’s time to sell off some of the family silver.
