I don't think this is generally true. It's very common for US grocery stores to have freshly baked bread, and there's always a huge variety of prepackaged sliced bread, it's not just like sugary wonder bread or something. You can also just go to a bakery. Not sure how accurate this site is, but it looks like the US and UK have about the same number of bakeries per capita. https://www.ibisworld.com/industry-statistics/number-of-businesses/bakery-cafes-united-states/ https://www.ibisworld.com/industry-statistics/number-of-busi..., https://www.ibisworld.com/united-kingdom/number-of-businesses/bakery-cafes/14650/ https://www.ibisworld.com/united-kingdom/number-of-businesse... Certainly there are some places where your only option is a dollar store that probably won't have anything good, but I've been a lot of places in the US and I've never found this to be an issue.
