Americans found lots of values in Starbucks coffee because Americans have no concept of coffee that's simultaneously black, not bitter, not acidic, and sweet. It would be wrong to blame Starbucks for that, they're a symptom, not the cause, but yes their coffee sucks. As it does everywhere else in the US, the country that thought that percolators were a mighty fine idea.

(And yes I know you guys invented the Aeropress. Good thing, good job, good coffee (with proper beans), now also use it).
