We should use u6 to determine unemployment accurately which would put us in 15% ish right now.

If UE is a pie chart, you can't use the same numbers if the pie gets smaller. When Somone runs out of 99 week benefits and still can't find a job, they don't count that person in the UE numbers.

People employed part time but want full time and can't find it are also counted as "employed"

That's just flat out misrepresentation
