Enjoy your evening gentlemen

Just a quicky, when I left the pit I had an estimated £23,000 in my pension fund.
AFIAK it's currently estimated at about £15,000.
Is this the typical small print, investments can go down as well as up.
When I'm 60/65 will this have diminished to considerably less. £2000
Who's taking my pension money ?
Why are bankers allowed to make decisions using my money and leave me with nothing.
I paid into the MPS, who's creaming it.
Greatrix fell for his own greed. Seperate thread on here somewhere I think.
