Easy. Just keep spending on marketing and bribing stores to give them preferential placement.
You think they were a premium brand, that did not compromise on quality. Do you have any evidence of this?
Or did you believe it because they told you they were, and because they charge more?
This is the beauty of unregulated free markets. With no actual baseline for quality, it's often easier to dupe people into believing that you're not cutting corners, than it is to not cut corners.
And for all intents and purposes, this is an unregulated market. The inspectors have been finding a horror show for years, but couldn't shut it down because, well, that would impact the meatpacker's bottom line, and some apparatchik somewhere is getting paid off to make sure that won't happen, and he will make your life very unpleasant if you try to make waves.
Regulations with no teeth aren't regulations. Everyone's mad at Boar's Head, but the actual problem is in the systemic failures that lead to the plant being open after it failed inspection after inspection.
The business should be liquidated, it's current owners are clearly incapable of operating it.
