Everyone needs to read the intro of Henry Hazlitt's Economics in One Lesson.

In it, he explains the disconnect between the usefulness of economics as a method, and the usefulness of the economics predictions people see on TV.

The problem is that economics, moreso than almost any other discipline, deals with policies that result in winners and losers. Because of that, interested parties are incentivized to manipulate the economic analysis in their favor, either by distorting the data or by bringing on friendly experts that support their position. And because interested parties are the most incentivized to get their message out, that's who you tend to see in the press.

There isn't as much of a market for neutral economic analysis, unfortunately.
