I see your points; I guess it's a matter of perspective to some extent. Personally for the sake of those returns I'd rather have my money in cash or gold but again, depends on situation, quantities etc.Yes, it is a pittance but a small pittance is better than nothing.
I must admit that I made the assumption that people do keep some more liquidity available for short-term needs. I can't imagine anyone not. i think my point is that short-term fixes are better than the insecure, earning nothing, cash under the mattress method.
I agree re the dismal long-term prospect of interest rate rises. It has cost us dear since the 98 crash.
We too got caught by the Landsbanki debacle - although it eventually came to a satisfactory conclusion as you know. The FSCS processes are more streamlined now in the wake of it.
We would consider ourselves more prudent than lucky to be in the situation that we are.
Wasn't wishing to diminish your prudence with my last comment; however I think it's a given than most people in subsequent generations won't have the same opportunities that yours did though.
