Society is only concerned with cost, regulations are weak and rarely enforced and companies are operating in a capitalistic market where they can't compete unless they squeeze every last cent out of each animal. That's hard to change as lots of people have an interest in keeping the status quo and the citizens who vote don't have the time to read everything that comes their way. We can't expect that society will wake up, that people will start voting with more conscience or that everyone will go vegan.
Lab grown meat (or growing brainless animals or something similar) is a technological solution. When it becomes cheaper than normally-grown meat and similar in quality, the atrocities committed in the farms would cease to exist as the farms themselves would cease to exist. The same market forces that are responsible for what's happening to the animals now would prevent any future torture.
