The only way meat is cheaper than a slavery free vegan (or vegetarian) diet is if that meat comes from a torture factory

a single counterexample would disprove this. also, torture factories don't exist.

Some of these factory farms are pretty torturous for the animals, like the scale of our meat production is way too high to be clean or humane, ESPECIALLY chicken.

Local meat is still worse for the environment than non-meat that was shipped across the globe

I don't know how you can prove this

Measurement of carbon emissions is a huge one but local meat is still usually better in that aspect, and it's also the people doing the local farming have closer to living wages usually.
