Isn't this a good example of it being more accurate to blame the system that allows the spending?

The general assumption should be that at least some people/corporations will do ANYTHING that is legal as long as it is profitable.

A system is also composed of its pieces. There's plenty of blame to go around. Trying to blame entirely the system and absolve the company of its immorality is nihilistic. Stop thinking that companies aren't to blame just because they take advantage of a bad system.
