That was actually a very nice read! I just finished the book and certainly remember the meat factory scenes the most, but couldn't help but feel Upton would have been disappointed from the message he was trying to ultimately convey.

Don't let the perfect be the enemy of the good. I know he was disappointed with the outcome, but it was still an improvement during a fairly capital-friendly administration.

(Though Teddy Roosevelt certainly pissed off monied interests when he felt they were acting immorally)
