As an American, I agree with you. Most things we call chocolate are painfully and literally disgustingly sweet. We have plenty of good chocolate too. However, anything darker than about 40% gets called "dark chocolate" in America, which is just stupid, so even that isn't a sure sign that it's not loaded with sugar.

Most grocery stores will have a few dozen chocolate bars in their candy aisle that actually say a percentage on them. Not only does this tell you what's not sugared to death, but companies that do this tend to make higher quality chocolate anyways. Anything 70% and higher tends to be tasty.
