You are correct. The US Revolution marked the beginning of the greatest free society in the world while the French Revolution marked the beginning of communism and the murder of millions of people simply because they had money or intelligence.
It also marked the beginning of a few other things:
- passports
-"total war" (War involving the entire population of a nation)
-the draft
-hotel registration (you know, when you check into a hotel/motel you have to give your name, etc.)
-books required to list the name of the author, publisher, the date & place printed.
-the restaurant. (Not just an inn or bar that serves food, but a place whose only purpose is to serve food. This came about b/c with the Revolution a lot of privates chefs found themselves w/o employment or employers.)
- the terms "the right", "the left" and "the center", all referring to where the conservatives, the liberals, the the undecided sat in the Assembly Hall.
- the rise of the 4th estate (the press) and its ability/desire to influence politics.
