£3 billion assuming UK population of 65 million is about £46 each per person. I suppose we could go the other way and remove the subsidy totally and see what happens. If the status qou us maintained it will cost the family of four £200 a year which would be on the shopping bill but their tax bill would reduce.
So you say 'way more money than currently' well unless there is profiteering by farmers without subsidy it will cost about £200 a year more - is that way more? Offset against the tax saved. And it would mean maybe less direct transfer of 'ordinary folks' income to large landowners as currently happens.
Hey ho good debate.
You are missing the point, , over 30% dont pay tax other than VAT, and they would be the ones hurt most by rising food prices
