I found the style rather forced, and the overflowing didactism wouldn't have gone well even if I could agree with the message. Which is, let me tell you: don't try to better yourself, if you were born poor and without education don't try for an education for your kids, 'cause for that you need money and money is evil. Is that really okay with you people?
A minor beef I also have here is about making moral judgements on nature, like calling the scorpion evil and making out it'd really love to poison this sweet innocent kid, as it has no other purpose in life.
I guess that will be all I need from Steinbeck: I liked Of Mice and Men a lot, but from there it went downhill, quick.
