The New York Times has an interactive budget solver. On my first try, I "solved the budget."
I only selected the options that I thought sounded like fantastic, great ideas to me. The thing is, every option is pretty reasonable and worthwhile. Surely Congress will be able to implement some of these kinds of changes if the NYTs is able to compile such a lengthy list of only reasonable solutions.
