A few billion by the looks of the last couple of years.

Easily argued more in a centrist manner that true unions were the ones trying to preserve life in the factories and down the pits ( I mean back when kids didn't see daylight even on Sundays) and the establishment/right were the tory landlords sending them down, forcing pay to be spent on-site in tuck-shops they owned, etc.

The pendulum doth swing one way then t'other and far too far currently.
