The theory that TIPs protect you from inflation is flawed.
It is common knowledge that the gov cooks the books. The published numbers would be laughable if they did not cost us so much money. Real inflation is closer to 12% than 2%. But adjustments made to tips will be based on false gov data. So your tips only partially protect you.
Buy gold and stable foreign currencies like FXS, FXF, or FXY.
