I just had occasion to quote: There is hardly anything in the world that some man cannot make a little worse and sell a little cheaper, and those who buy on price alone are that man's lawful prey.

In checking the wording, I found this site, which claims, apparently on good authority, that it isn't Ruskin. He would have agreed with it, whereas it is not clear to me that Burke would even have said All that is necessary for the triumph of evil is for good men to do nothing.
