If we cut the speed limit to 30 mph on every road in Europe there would be virtually zero road deaths across the continent. We don't do it because it's not practical. This lock down is a temporary measure to buy time to allow the health services to prepare. We can't shut down economies for a prolonged period, it's just not viable. Business will soon re-open and the premier league is a business just like any other. They will try to do what's best for themselves, it's up to the government to tell them what they can and can't do, e.g. behind closed doors games etc.
TLDR; it's not a simple case of big business doesn't care if people die and money means more than lives. Businesses try to do the best for themselves within the constraints of the law.
By the way I'm not having a go at you but I fear there's going to be a lot of public outrage when things re-open and people are still dying of C-19. It's not possible to avoid this IMO.
