Remember too that with an investment you have to add fees and charges onto inflation before you will make a real penny. So the inflation rate for investments is always higher than it is for cash. Always.
If a financial sales person mentions inflation, ask what guarantees they will give that the value of your investments will beat inflation. And when they say things by way of a 'reply' just repeat 'yes but what is the guarantee?' Then put it in cash.
Remember too that if you have debt then inflation is your friend. And who has the biggest debt? The Government which says it wants to control it!
Enjoy your cash!
