Indeed. If you or I run a triangle shaped Ponzi scheme, using new members subscriptions to make previous members rich, we'd be arrested. Yet that's exactly what the Government does.
I make no apologies for my police pension either. It was hardly a freebie, having shovelled a full 15% of my salary into my pension since I joined the Army. How many people save even half that, yet then complain their pension isn't enough? For me it's compensation for nearly 30 years of military and police, crap pay, poor conditions, being shot at (once in the army, once in the police), being blown up (once in the army), being stabbed, being assaulted multiple times, including breaking an elbow which required 2 lots of surgery and a year of recuperation (and it'll still never be right), dire hours and mediocre pay. I'm not complaining, I made my choice, gritted my teeth and did my duty, and my sole consolation for all that sacrifice is a pension.
If I didn't like if I could have gone on the boats in the Indian Ocean doing anti piracy work for £200k, or BG work for a similar amount, and worked 3 or 4 years and retired. Or I could have used my degrees to probably push me into 6 figures (was offered £80k to work for Hughes first time I speculatively applied) so having foregone such financial opportunities such as those to serve my country I'm quite comfortable taking my pension by way of some small compensation, even if that pension was hardly a freebie and cost me a lot of money over the years.
If it were not for that there would have been no incentive to devote the best part of my working life to public service. Might have done a few years in each, but there would have been no reason to stay long term, gain experience, learn skills and specialisations for which I didn't get paid any more. It takes about 5 years to become a fully rounded and competent front line copper, and without the pension there is no reason to stay beyond that. Indeed, the modern pension is pretty average and as a result the incentive is no longer there for most officers, so turnover is on the increase and the average length of service that the average officer now holds is a little over 6 years, barely dry behind the ears, and the Government is slowly getting the police service it deserves as a consequence. Good luck to them.
