Congressional Budget Office (CBO) projections provide valuable insights into how a big chunk of your income is being spent and reveal the long-term consequences of our government's current fiscal policies—you may endure them, and your children most certainly will. Yet, like most other projections looking into our future, these numbers should be taken with a grain of salt. So should claims that CBO projections validate anyone's fiscal track record.

So much can and likely will happen to make projections moot and our fiscal outlook much grimmer. Unforeseen events, economic changes, and policy decisions render them less accurate over time. The CBO knows this and recently released alternative scenarios based on different sets of assumptions, and it doesn't look good. It remains a wonder that more politicians, now given a more realistic range of possibilities, aren't behaving like it.

First, let's recap what the situation looks like under the usual rosy growth, inflation, and interest rate assumptions. Due to continued overspending, this year's deficit will be at least $1.6 trillion, rising to $2.6 trillion by 2034. Debt held by the public equals roughly 99 percent of our economy—measured by gross domestic product (GDP)—annually, heading to 116 percent in 2034.
