And as for your snark, no, many French people do not speak English, and a fair number resent Americans going around like they own the place without making even a cursory attempt at being polite.
I speak French, German, and a small amount of Greek (enough to order a coffee and read a map). That's no use when I go to Italy or Spain or Poland or Latvia or Sweden of course, so we just speak English.
The big difference between europe and america is the market. The US is a homogenous culture with a single language and single desires with 350 million people. You can launch a product in the US based on US culture and assumptions and reach a massive economy
Launch it in Belgium and you've got a fragmented market. Not just the language, but also the culture -- expectations in Belgium, Romania and Norway are all very different.
On the other hand, as a foreigner, I have been to tiny villages in Sweden where even 70 year old grandmas know enough English to communicate.
Oh they'll understand. They will just pretend not to. It's France.
