Labor Force Participation is Secular: Unemployment is Cyclical!

Updated data at the request of Andrew Sentence on participation and unemployment in the U.S.  
Business cycles are about unemployment; not about changes in the participation rate.

See my twitter posts today on this topic. 

If people choose to look for a job; that's their business. If people can't find a job; that's our collective business as a society.
Participation is a voluntary choice.  Unemployment is not. 
The idea that unemployment is voluntary is classical nonsense.
Anybody want to explain to me why they think labor force participation is a cyclical phenomenon?
Participation is not cyclical! Unemployment is!  
The secular trend in participation dwarfs the cyclical movement. That's an important fact!
