This is akin to having more IRS agents policing tax fraud. Simplest way is to ensure H1Bs are at 90th percentile of the market for salary. H1Bs are supposed to be for engineers that are very hard to fill so making their salaries high ensures that that gets met. You really want them? Pay for them and be done. Simple to enforce and simple to get the H1Bs for folks who really need them. All birds killed with that stone except for the company's desire for cheaper labor.
