Although the figure is completely made up I certainly agree with the sentiment of this point.
I have worked around the public sector for a number of years. I just couldn't imagine a lot of the people ive worked with in a 'proper job'.
The public sector is vast, from doctors and teachers down to pencil pushers working in the local council office. I'm sure there's lots of decent hard working people in there, but most I've come across have been fuckin useless
Maybe that's because direction and management is 'clueless.' And the never ending policy changes without proper training is ridiculous, ill thought through and woefully inadequate.
And I've seen a few join us in middle management roles from the private sector in recent years, and they can't hack it either.
