Henry Blodget looks at the lack of income growth for the bottom half of Americans and explains the problems this causes for the economy.
That would be ZERO income growth for the bottom half of the US population, and very little for the next 40%, so 90% of the US population has seen little to no growth.
Why this is bad, is because the economy is driven by those that spend money and the bulk of the people who spend their money are the bottom 90%, yet they have little money to spend.
This means that the rich could be making even more money if income growth was spread out more. But the corporations are not allowing that to happen, probably driven by quarterly profit requirements, and the majority of the populations suffers as a result.
