I agree. The banks are eating up all the tax advantages that the government gives us. Cash ISAs are a complete waste of time.
It is hard to believe that the government doesn't see what is going on. Does the government allow it as a secret, hidden subsidy to the bankers? Stealing from the poor to give to the rich you could say.
On top of all the tax and quantitative easing (printing money) that we give them...
I am in the same position. Like you, I keep my ISAs in the belief that I will get tax advantages some day. But for now they are a joke. Time for an expose...
