The solution to this is to compensate people so that they don't take the chance and leave. "I'm already making X here, why would I want to risk that?". This naturally distributes wealth a bit more evenly between the workers and the owners.
You also need to think about your scenario. If the employees are able to make the same thing at half the price to the customer, that is a HUGE gain for the customer. If another breakout crew does the same, that's half the gain again. The customer wins, but it can't go on forever, at some point it's not worth the breakout risk.
