The Roman army had a technique called "decimation". If a legion had a major infraction, the commander would execute one in ten of the soldiers. The survivors got a clue and straightened up.
Smack one in ten, or one in one hundred lawbreaking businesses, and the rest might get a hint.
And never underestimate the resolve of the US government to actively pursue fines. Have a look at the zeal of the IRS for example.

This is America and not the Roman Army and that where the big difference is.
