I use cost of living calculators. As for percentage of income, that is not a direct comparison. That factors in rent and whatnot. Also, you can cherry pick things like Coke that are more expensive, but that is deceptive.

My point is that the lower costs and higher quality being delivered to consumers in countries with GMO labeling show that it does no measurable harm.
Ah ok, where to begin...
First of all, using costs as 'percentage of income' isn't quite as wrong as you think it is... An overall higher standard of living (or higher GDP) in one country will mean higher prices for everything; comparing items as a percentage of income eliminates that factor.
Secondly, I find it extremely ironic that you are complaining about my deceptive 'cherry picking', since your whole argument is based on deception. There is a reason for "cherry picking", and I've already touched on it...
not all products are impacted by GMOs.
Lets take a look at your site... it points to the daily cost of food in the U.S. being higher than in Germany/France/etc. But you know what? part of that cost reduction is because things like Lettuce and Oranges are cheaper.
And there is no GMO equivalent to those items. On the other hand, the items that I "cherry picked" (beef, coke, etc.) definitely
do have a strong GMO input... through the use of genetically modified corn. Those items are relevant in doing price comparisons. Items that have never been subject to GMO modification are irrelevant.
And here's another point... your particular web site involves
consumer reported prices (i.e. what you pay in a super market). But, European agriculture is heavily subsidized, to the tune of over $70 billion per year. Admittedly, American farmers are subsidized too, but the subsidies are much lower (around $20 billion). Even accounting for the larger population base in the European union, European agriculture still receives higher cash.
So while you may pay less in the supermarket, the real cost of the food is higher; they just pay though things like income tax.
