Most-quoted passages
The sentences later courts lift from this opinion, ranked by how many decisions quote each — the parts of the opinion doing the work.

“Much of the argument is based upon the supposed wrongs to the employee, and the alleged injustice and arbitrary character of the legislation here involved as it concerns him alone, contrasting an employee in a shop with five employees with those having less. No employee is complaining of this act in this case. The arguments based upon such discrimination, so far as it affects employees by themselves considered, cannot be decisive; for it is the well-settled rule of this court that it only hears objections to the constitutionality of laws from those who are themselves affected by its alleged unconstitutionality in the feature complained of.
