Well post 1893, sure.

But even today, until we had a new class of mega-rich, let’s call them Billionaires - the nuevo-riche were always quick to be thrown under the bus by old money.

Now the power dynamic has shifted, but the billies will still, and do, chuck millionaire cronies to the crowds if it means avoiding responsibility and comeuppance.

Sadly/Unsurprisingly no-one goes from peasant to lord, short of being family of Jean of Arc.

I don’t think there’s another case of peasant to upper nobility in a single generation.

While true, it was next to impossible to keep track of people - there were no borders or division.

If a lord was offering a better deal (or their old Lord was too despotic), serfs could and would pack up and leave and there wasn’t much their old lord could do about it.

The other part of people moving to the towns was inventions of new tools such as better looms and improvements in metallurgy to make more precise tools.

Yes, that they don’t/didn’t have enough freedom is always a legitimate reason to invade an occupy a nation.
