The very low paid didn't enter the tax net, and the very highly paid avoided it (the very high earners tend to have a low effective tax rate compared to PAYE workers).
I haven't had a chance to read the document yet. I was expecting the change to pension tax reliefs to be in it - I think I flagged it on here a few weeks ago as effectively a pay cut on the public sector - but didn't realise it went further for the public sector. Despite the hype, some public servants would be better with the standard contributory pension, so that'd be a tough hit. Edit - Dodge, can you give the page for what you said earlier, as I can only find about the general reduction of pension reliefs to standard rate, and how much extra in pension levy because of that rather than a specific change for the public sector having no relief?
