The Economic Policy Institute has a policy memo from 2006 that says a lot about why the economy isn't working for most of us.
Here's the gist: Productivity has gone up (read: people are working more and harder), but wages have remained steady or declined.
Company profits have risen, but wages have remained stagnant (read: Stockholders and corporate managers are making money, but workers are not)
Debt is at an all-time high. (read: People are financing their lives because they have no money to pay for food or bills)
Poverty is increasing (read: Greater divisions between rich and poor lead to economic dysfunctions, viz., economic slavery at the bottom)
Health care costs are rising while wages are falling. (read: life is cheap and getting cheaper, but your one-time doctor is doing well).
This sort of stuff tells me that anyone stupid enough to support a politician who advocates more of the same should be taken out back and horse whipped. (read: McCain)
