I disagree, Dennis

, the problem is a lot more complicated. The imbalance in wealth doesn't cause specific food inflation. An Indian steel magnates asset wealth increase of several billion doesnt push up the price of cheddar cheese (unless he's buying it all up). Many countries with the largest wealth imbalances have the cheapest food prices.
Coffee and chocolate have gone up globally due to weather and harvest issues. Meat has gone up in the UK because demand has risen, due to population increases of several million in five years, and farmers dont have the immediate capacity to produce more, and at the same time, Brexit has made imports more difficult.
It's supply and demand driven inflation, where food is concerned. If you asset tax all the millionaires and spread the money equally, food inflation will still occur if there's a supply issue, or if demand increases.
