Imo it's just really easy to switch stuff like burgers, nuggets, chicken wings, chicken breast etc. over to a (good) plant-based equivalent, I don't feel like I've lost anything by doing that. It would already remove a lot of environmental destruction and animal suffering without people going fully vegetarian or vegan.
Not saying those efforts can’t be done in parallel, but subsidizing vat grown meat is necessary as well.
Yes, I agree with that and I'll be happy when it gets affordable.
That gets difficult when billion dollar industries are involved, especially multiple. Some politicians will oppose the corruption, but the corporations will just fund the campaign of other politicians that are willing to act in their interest.
Transparency and a vigilant civil society with consequences for scandals can mitigate that somewhat, to varying degrees. But ultimately there's corruption in every government at every level of governance. Capital interests always find a way, unfortunately.
