The problem with the chart: why does a salad cost more than a Big Mac

This chart is getting alot of publicity on blogs that I read:



But as this post points out, Why a [U.S.] Big Mac costs less than a salad : Contrarian, it is "chart junk". Specifically, why is a pyramid used? At best it should be a bar. But using a pyramid, you can overemphasize subsidies to meat and dairy and visually distort the actual subsidy. That isn't to deny that meat and daily don't get alot of subsidies. But there should be no need to change the chart to represent that.

I would also argue that a salad in Burger King -- where I eat salads -- does not cost more than a Whopper (roughly equivalent to a Big Mac). So I don't know if the comparison holds. A salad in a restaurant other than a fast food restaurant will cost more than a Big Mac. But that has to do with alot more than meat and dairy subsidies.

That all said, I think it would be ideal if people ate more vegetables.
