I read that one of the reasons for the transformation of these crustaceans into luxury items related to how there was such an abundance of lobster that they had to start canning it to preserve it, otherwise they'd have to start throwing it out. This led to fresh lobster becoming a premium item. At some point, someone saw a business opportunity, and the rest is history.
Ha...we aren't taught much American history, either!
Seriously, there's always a bit of a debate about how much children are taught in school. There always seem to be areas that are glossed over or simply skipped. Most of the education about that time period relates to the formation of the country. I imagine it's even worse when it comes to European history for European kids (we only have ~250 years of history, whereas you have....a lot more years).
