Years back Google and Apple conspired to illegally fix wages and were caught no less red handed, including executives emailing to keep the program out of email because it's illegal. The conspiracy even used threats of ruining other competitors with patent claims to force them to participate.

The fines and judgement they paid were but a tiny fraction of the cumulative wages they stole. The lesson was that wage theft is profitable.

Until we start imposing a corporate death penalty in situations like this there will be no reason for companies to not simply do the economic calculation and decide the defrauding their employees is the right thing to do for their bottom line, one that can be optimized by lowering the risk of prosecution by better obscuring the crime or building up a legal team that can tie up the largest of nation states in court for decades.
