Less pressure to look amazing - to show a lot of flesh if you're female, spend a lot of time on personal grooming, be muscular and smooth if you're a man.
Judging by Curley's wife and by the descriptions of men and women, I don't think this is true. I don't think it's true of the 1920s more generally, either.
Less pressure to achieve in all areas of life.
In the middle of the Great Depression? Less pressure to achieve?!
An unrealistically high expectation on men to have a stiff upper-lip.
Yep, I'll grant you that, possibly ... is this 'better'?
Less pressure to be a perfect parent; to provide extra-curricular activities for our children, to be endlessly patient, to label them and measure them.
I don't see how you get that from this book and I certainly don't see how you get it from 1920s America.
I get that I am talking about a book you've said you don't remember much about, but I do think it matters. You're assuming (I think?) that something in the past must be better than today and that we must be able to point fairly to positives and negatives. But that falsifies the past, and constructs a fake image of a time that never existed. It's this sort of image of the past that people trot out time and again when they're justifying how, back in the day, sure, we didn't have equal opportunities but wasn't everyone happy?
I think it is deeply irresponsible to say that if you don't know it's true and if you can't point to specific examples.
I find it particularly difficult to swallow about the Great Depression. My overwhelming impression is that it was an incredibly difficult time to live in. People were dying - actually starving to death - in what should have been some of the richest countries in the world. The pressure to achieve must have been appalling. I simply don't believe there was less pressure on physical appearance, either - this is the era when women bound their breasts to make themselves look flat chested, dieted and ruined their health, and when vaginal douces that burned them were being put on the market. This is when black women were being sold 'skin-lighteners' that were toxic (and yes, I know this still happens but it shocks me).
I'm not denying it's good to look at the past and not be uncritically negative but why be uncritically positive?
