> Which doesn't make it false of course. But it does have the same neatness that drives urban legends, and in a place like HN we should be wary of this.
Agreed. To restate in less argumentative terms, the claim made that:
>the most convincing evidence that it was very hard was that early mines and factories were easily able to recruit all the workers they needed, despite working conditions we know to have been harsh.
to be convincing must show that:
(1). there was a real alternative between peasant life and industrial life,
(2). that peasants made the choice with at least a decent understanding of what factory life was like.
1 is, as you state, debatable which weakens the claim (it certainly is not evidence in the affirmative). On 2 I don't have the expertise or the citations to state one way or the other, but I would love to see some evidence on either side before placing faith in the claim.
To generalize, I would say that any argument that "A is better than B, because lots of people from B prefer A" must at minimum meet the test that: it is a true choice, and that the people making the choice have enough information (informed consent). Additionally, I do not consider such arguments truly convincing, in and of themselves, even if they meet both tests because populations can make poor choices (cigarettes, electing bad politicians, buying an inferior product, etc).
