I share a virtual neighborhood with a legion of Times reporters, editors and columnists who know more than I will ever know about business and economics. (Look! Right over there: a Nobel-prize-winning economist!) In this humbling company, on this intimidating matter, who am I to tell anyone what to think? And so my plan was, frankly, to avoid the subject.

But while there are things a columnist can ignore (if Kim Kardashian ever features in this column, just shoot me), our failing economic ecosystem is not one of them. So for the past several weeks my airplane and bedside reading has consisted of sexy documents like “A Roadmap for America’s Future” and “The Way Forward” and “The Moment of Truth” and “Restoring America’s Future” and “Living Within Our Means and Investing in the Future.” I’ve also reached out to a few economists respected for the integrity of their science and their patience with economic illiterates.

The first thing I gleaned from this little tutorial will probably not surprise you: There really is a textbook way to fix our current mess. Short-term stimulus works to help an economy recover from a recession. Some kinds of stimulus pay off more quickly than others. Once the economic heart is pumping again, we need to get our deficits under control. The way to do that is a balance of spending cuts, increased tax revenues and entitlement reforms. There is room to argue about the proportions and the timing, and small differences can produce large consequences, but the basic formula is not only common sense, it is mainstream economic science, tested many times in the real world.

So what’s the problem? Why is our system so fundamentally stuck? Partly it’s a colossal, bipartisan lack of the political courage required to tell people what they sort of know but don’t want to hear. Partly it’s a Republican Party that, for its own cynical reasons, wants no deal with this president. Partly it’s moneyed, focused lobbies that swarm in defense of specific advantages written into the law; there is no comparable lobby for compromise, let alone sacrifice.
