Seems like a very simple solution is begging to be utilized here... Make everyone in government earn less than 15,000 pounds, and everyone's happy.
Or pretend that you're doing income taxes -- Everyone under 15,000 gets a free ride, those who earn up to 75,000 have to pay a quarter of their salary (even those who make 15,001 pounds), and everyone who earns more than 75,000 pounds has to turn over half their salary back to the government. Which means if you're earning that horrid 75,001 pounds, you just got a massive paycut, but the guy who's earning 74,500 is laughing at you.
Seriously, END PUBLIC EMPLOYEE PENSIONS. Period. They can have the exact same benefits as any member of the public gets along with paying exactly the same amount the public pays into the system. No more 'more equal' animals in the farm. And if that garners strikes, which it will, of course, fire them and hire the public who's been looking for jobs and will gratefully accept the same deal that they'd get anywhere else.
