Were you trying to make a relevant point, because I don't see it.
Are you talking about Bangladeshi livestock?

I'm talking about the west. I really don't give two fucks about the rest of the world.
The point is that when it comes down to purely economical reasons, the free market in majority doesn't prioritize ethical or humane treatment of anyone or anything so long as they have a way of getting away with it - if corporations can't employ actual slaves, the next step is to source all their products as cheaply as possible, i.e. from slaves.
You can extrapolate this to where meat and dairy companies source their products from - typically, as cheaply as possible. So then you just have to ask basic questions:
Is it cheaper to provide more or less space to animals?
Is it cheaper to provide or not provide anaesthetic to the tens of thousands of animals that require surgery?
Is it cheaper to provide or not provide adequate and professional veterinary care to animals (bearing in mind that veterinarians are very expensive)?
Provide food that will actually keep them healthy?
If we can give chickens growth hormones to swell their size and get more produce in a shorter period of time out of them, is it cheaper?
It's totally naive to think that mere free-market economic pressure would prevent stuff like this happening. Most corporations don't even treat
people like sentient beings if they can get away with it, what makes you think they're going to extend that courtesy to animals.
Any extra expenses that affect the bottom line of monthly P&L report is going to come under close scrutiny. Corporations are all about that bottom line. If they can find any kind of way to maximize profit, even if it's at the expense of some person or animal - they will. It's the entire MO of a corporation: productivity and profit.
And economic pressure doesn't prevent
any of that. The only reason it does nowadays is because humans can take people to court, we have media and industry watchdogs. But cows can't take people to court, so it's not unbelievable that corporations would be profiting at their expense.
Economic reasons being what prevents the mistreatment and cruelty towards livestock is surely the most naive one I've heard yet.
