"Really? I know people with PhDs who struggle to be employed."

Because a lot of PhD's learn a whole lot of theory but have no practical applied knowledge.

Not true - they have a lot of practical experience. Or maybe they have too much ("overqualified").

They sure as hell know alot. Too much probably. Most real world jobs aren't that difficult, you don't need to prove whats already known you just got to use it. PhDs are usually more research oriented, and the number of research jobs are fairly small.
