In the meantime my children and grandchildren are going to have to live with that economic cost in the longer term
Mine are going to live with the economic opportunity. So are yours. Stop being afraid and start taking hold of the opportunities available.
My family have already (financially) done very well out of remainer panic. We remortgaged at all time low base rates, and fixed it for the life of the loan, moved out of the £ and then back in once the panic had set in, thus addind substantially and tax efficiently to our assets. If you were too busy panicing or incapable of thinking things through to do the same then I can hardly be blamed for that.
The end of the next labour government is going to make my family rich beyond anything I could have comprehended growing up. Those voting labour not so much, but again, I can hardly see how that will be my fault.
