While what you say might be true, I've got a few things to add.
1) £2400 is actually a decent amount of money when you are retired and have no mortgage or other dependants to pay for. My parents pension is less that that a month and they do absolutely fine, they can even afford to have the heating on
2) I won't be betting my financial future on the hope that the government will give me a handout when I retire, a pension is only one small part of my future financial plans. Besides I won't be here when I retire anyway, I'll be living in a warmer, cheaper country where my money will go a lot further so am I bleak about my future pension prospects\retirement. Not in the least, I am positively looking forward to it.
