I'm wondering where you live that your costs have gone up so much. Inflation is extremely low, most energy is a lot cheaper now than it was eight years ago in most places, food is about the same minus some drought-effected things that I'm pretty sure aren't Obama's fault, and taxes are marginally higher for people making a lot of money (

Are you sure this is about Obama?
