As for modern France and their propensity for rioting over minor labor disputes, who wants that either? Sure a narrow slice of the population gets early retirement but the youth unemployment rate is 20% and it is increasingly hard there to get onto a career ladder that would afford you an early retirement.
It's all well and good to credit the end of child labor in the US to unions, even though it was the progressive movement generally that ended child labor and not unions, but whatever. That said, the American union movement was a powerful force FOR segregation and actually caused a real drop in wages for black workers in northern cities in the 1910s and 1920s, so I think it's important to be honest about the whole history.
well, that's the only way to deliver the message, so yeah, I want that.
In France, I can go to lunch and not think about work. Here, I have to explain that "no, I won't eat lunch during this meaningless meeting to save time" every time I've invited to a meeting during lunch.
Some parts of the old elites ended up kind of on top at the end anyway, however in a drastically different situation - citizens had rights and power at the top came from below, not above (divine right was no longer a thing). So massive difference regardless of the title of the person on top.
Voluntarily is a massive stretch. Even more so when you consider that many that returned after the Restauration tried to get "their" lands and titles back - so it was only the threat of violence that made them abandon everything and run.
The Vendée uprising like many such uprisings was sparked by the Levy Decree(levée en masse) which was a response to the Girondins stirring up a stupid war for "national unity".
