I make no secret of the fact that there is a big soft spot in my heart for the tremendous gains of the labor movement in American history and a big sad spot for how certain unions — such as those representing meatpackers  and agricultural workers — have been all but decimated.
Since many — probably most — of my ancestors made their way in the world and in this country as laboring folks, I am proud to acknowledge that the privileges I have had I owe to their hard work and struggle to create an American middle class.

I can't resist pointing out that Katherine Paterson (the author of the first two novels) is a former Presbyterian (USA) mission co-worker (what I currently am). I'm afraid I idolize her writing a bit. What a storyteller!
And four of the five are young adult (YA) novels. I can't help it; that's a favorite category of mine.
Bread and Roses, Too by Katherine Paterson 
The Jungle by Upton Sinclair 
(It's less about nasty meat than textbooks might lead you to believe!)
