IN a little over a week, President Obama will send Congress his budget for the 2012 fiscal year. The budget is not just a collection of numbers, but an expression of our values and aspirations. As the president said in his State of the Union address, now that the country is back from the brink of a potential economic collapse, our goal is to win the future by out-educating, out-building and out-innovating our rivals so that we can return to robust economic and job growth. But to make room for the investments we need to foster growth, we have to cut what we cannot afford. We have to reduce the burden placed on our economy by years of deficits and debt.
