Federal Reserve Bank of Kansas City president Esther George exemplified the sharp internal divide that exists within the Fed when it comes to policies like quantitative easing, the Denver Post reported.

During a speech this week, the Fed bank president said accommodative policies may be creating new market bubbles that could eventually curtail job growth and the overall economy.

The Detroit Post covered George’s speech Thursday. George’s viewpoint contrasts with Federal Reserve Board governor Janet Yellen, who said she believes quantitative easing has been a success.
