Lol, yeah that definitely summarises people like Mike Ashley. There definitely won't be tons of bosses who will do the absolute bare minimum they are forced to, while trying to do even less than that. They will definitely all care about those employees they never previously a gave a shit about while they exploited them in every way they could get away with.
For the record, I've been working this whole time with a boss who is a good guy so we've been doing everything we can, but is naïve beyond belief to think everyone will be like that. If that was the case then we wouldn't need employment laws or guidelines for anything, because apparently companies are all ran by "intelligent people who understand what is needed". It's not being argumentative, it's common sense that you release the guidelines on how to open your business safely before you let people open their business.
