Cost of Living

Every time I do grocery shopping, I feel like the price of everything are higher that the last time I shopped which was like three days ago. Can you blame if sometimes I don't even want to shop just because I know I would be spending at least 70 bucks for few things we need such as milk, juice. eggs, bread, fruits, veggies, meat and etc...The cost of living is going up but the income of most employees don't. What is going on? I noticed that even car insurance policy are up, too! Is there still such thing as cheap auto insurance? Or is it a part of history now? I wonder what Obama has to say about it.
