The U-6 was NEVER the "real" unemployment rate, and Bush's U-6 was never 10%, bush had the BLS cook the numbers. See that knife cuts both ways!!!
The U-6 gives you the whole story about the employment situation. The regular jobless number, the U-3, can be very misleading, especially when many businesses have cut employee hours in response to Obamacare, and especially when we have so many people who are severely under-employed.
How would Bush have gotten the Department of Labor to cook the numbers? Do you have any evidence for that claim? How have the reporting criteria changed from when, or before, Bush was in office? Doesn't the BLS report the same types of numbers? So how could Bush have "cooked the numbers"?
Anyway, the central point is that when you consider the U-6, it becomes clear that the economy under Obama is performing markedly worse than it did under Bush--or under Clinton, or Bush Sr., or Reagan, or Carter.
