First cheap looking bread I found at Wallmart at $1.32, just over 4g sugar/100g

Another one, but with honey added, 8g sugar/100g

The closest I found was Cinnamon Bread, with 15.7g sugar/100g, which is expected as it's basically a dessert (though oddly, they list all of the sugar as added sugar ! What are those raisins made of??)

Here's a Dutch raisin bread with 23.2 g:

You won't find many families with Cinnabon as their bread provider.
It ranges from 3-10 grams iirc. Maybe even higher.
Let people get unhealthy food, that's not what we need to focus on, we need to focus on proper and correct labels on food so people can make an informed decision.
13g of sugar is absurd and is not normal bread in the US.
Even Bimbo, the poster child for "cheap nutrition-less imitation bread" caps out at 4g
