Optimism won't fix America's fiscal problems.
...What the discrepancy means, though, is that the president’s budget is, at best, a risky bet on brisk economic growth. His profligate spending plan is built around a best-case scenario, like a job-hunter signing up for a new car loan on the basis of a good feeling about a job interview. Maybe it works out. Maybe it doesn’t. But it’s not a responsible way to plan for the future. In the end, no amount of optimism will pay down America’s debts.
