Recall what the yield curve is measuring- it graphs Yield to maturity against a bond of maturity t, for different time horizons t. This yield to maturity is generally thought of as the interest rate.
First, the assumption is that we hold constant the risk profile of the bonds in question- think of just looking at the yields of T-Bills for different horizons.

The assumption is incorrect. The yield curve actually tends to be very steeply upward sloping when the economy is in a really bad shape, as the Fed inevitably lowers short rates to reflate the economye (e.g., look at the curve in late 2008). As the the economy heals and inflation pressure builds, the Fed tightens, which causes the curve to flatten (all else equal). Eventually, the tightening and/or capital flows result in a recession, and the curve steepens again as the Fed lowers short rates. Each of these monetary cycles may play out somewhat differently, but broadly they're very similar.

You have to be careful what you are interested in: the **current** state of the economy or the **outlook** (forecast). As haginile said a steeply upward sloping curve indicates a terrible economy now, but the bad times may be about to end and the economy abpout to recover from a low point. A flat or downward sloping is a good economy now that may be about to slip into recession soon.
