I doubt most of these laws are ever intended to catch the big fish -- like in business, the big guys always require special handling to process. For criminals, the big guys should already be so far disassociated with the actual activity that you're not going to catch them with normal crimes. For example, Al Capone was famously trialed on tax evasion, rather than any of the innumerable crimes he committed but couldn't be processed for.

The actual law simply isn't that notable in these cases, because the big guys have enough money to figure out how to navigate it liability-free.

Which is also why the law only really applies to the poor -- with enough time and resources, there's always a workaround.
