2. Recessions cause the destruction of money (Due to defaults, and lack of new loans). This causes deflation. If the new money created by the printing press does not exceed these deflationary pressures, you won't even get inflation, let alone hyperinflation.
3. Deflation is horrible, and is much more dangerous than mild inflation.
4. The printed money is currently chasing investment assets (Mostly stocks), not flour and ground beef. Our previous experience with QE did not result in the prices of commodities inflating - only the prices of investments.
Inflation is not the problem.
