One of the Two Things We Can Be Sure of

This article is short, and to the point - about tax reform. It makes sense, doesn't it, that all the tax reform in the world doesn't mean a thing unless spending is reduced? If we continue to spend a lot now, but cut taxes, it only guarantees a tax hike in the future, right? I know economically it's a lot more complex than this, if you consider the pros and cons of debt, the influence of the stock market, and the federal reserve setting interest rates, and on and on. Blah, blah, blah. I don't really understand how all of these things effect each other, but I'm interested in knowing why reducing all the entitlement spending is not a big issue (is it only because of lobbyists and the promise of a vote?). It makes sense that it should be cut. So why isn't it? Am I missing something?
