It is £4,300 and its an average, some will be even worse off. And we are part of a global economy, we will be sropping down the ranks, our ability to buy foreign goods (and we do lots of that now) and go on foreign holidays will become more expensive
You failed to answer me last time so I'll ask again - does your household have an income of £78k ? That's what that £4,300 figure is based on and even then the maths was corrupted by using the GDP in 2030 but number of households NOW ( rather then 2030 ). Keep quoting that figure but has been proven as false by so many people and bodies now you'll just look stupid.
