Well...yes, since what you were trying to say was apparently not clear to me.

How would I know that from the news? This graph shows dx/dt, as do most news reports. That is very different than dx/x. The given information makes no assumptions on total jobs available. 10% unemployment does not imply that the total jobs lost is equal to 10% of the total jobs out there. Some of those unemployed may just be entering the workforce and have never been employed to begin with. They would not even appear on this chart since their jobs were never "lost".
