The main point (I'm monomaniac I know :) is the unemployment measure.
The message is repeated repeated repeated all day long on all medias:
John and Jerome picked the OECD data I inserted into french and english wikipedia (which has survived all edits BTW), alone it is largely enough to convince anyone that economists MSM are not showing and studying the right data.
Each time I used this argument in discussion it had a big impact with everyone realizing within a few seconds (of silence) the scale of the "unemployment" lie.
It's easy to learn: OECD 2004 male 25-54 87.6% 87.3% 4.6% 7.4%. Use it each time you hear or read unemployment and can talk or write back.
You can also mention that in the USA one in six 70-74 year old is still working and the number is rising. More work/GDP is more well-being?
