Re: Revolving doors are dangerous...
A Eurocrat renouncing their "old French Civil Service" lifetime pension. You gotta be kidding me (you should look up some of the details - they came out in public around Brown bringing back the Dark Lord from Brussels).
IMHO this revolving door direction is all right. I do not see anything wrong in an ex-public servant working in the industry with some reasonable amount of non-compete restrictions.
The other revolving door is the dangerous one - where (especially in the UK), industry execs move into government and/or regulatory quangos without surrendering shares, pension, benefits and any of their vested interest. I can point to actual names here, but why bother - they are all very well known.
