Investors have become "consumed and blinded" by economic data, says Jim Cramer. We've been infected by the "hedge fund media complex," where traders are under the mistaken perception that the economy must remain weak to keep the Fed on the team, helping stocks go higher. "Don't fear good economic data," Cramer says. "When we see higher employment and a Fed that recognizes that growth, then we will start to get a real demand for money."
