1) Have you ever seen the inside of a slaughter house?
2) Have you ever worked there?
I used to work in a meat room and went to a slaughter house often. I have no problem with eating meat - still do. But to keep up with American demand (because no meal is complete in America without meat - and we are basically the only ones in the world that think this - and no it isn't cause were a super power) a LOT of corners are cut.
The first thing you do in a slaughter house for beef is use either a sledge hammer or a pnematic bolt driver and put one right between the cows eyes. That kills them about 60 percent of the time. Most other times is stuns them long enough for the second guy in line to slit thier thoat. But when your going fast - you can miss and not deliver the death blow to the animal. The third gentlemen in line takes the animal off the conveyor belt and hooks thier achillies tendon (after making a small slit) up to a hook where they hand upside down for the remainder of thier stay. About 2 of 10 end up coming to on this hook with thier neck partially slit and a hole in thier head and flail around until they eventually die - terrified and slow.
This is not to mention the condition that that animals are kept in in factory farming settings. Animals are often fed the remains of the other animals that have died. In some cases (a good percentage) veals cows never leave thier pen (which is just a little bigger than them) and thie legs never develop. They live in thier own feces for thier entire short life until they get the bolt to the head like the rest. Here is a site to help you out.

I think the main problem with your post is that you are asking econmical questions - not ethical ones - but you are proposing to answer both types.
1) If there is demand - we MUST fill it - by all means necessary. I am sure you don't feel the same way about hookers, hitmen, and drugs.
2) If an animal kills its prey - it is okay for us to kill our prey by all means necessary. I am sure you see the different between the wanton torture of animals by humans and the 'kill only to eat' mentality of animals. However, you want to remove deontological ethos from this debate entirely.
3) It is still entirely possible to create something inherantly good - and yet have that thing have free will. In fact, the majority of religions believe this about humans. Within free will the person has the ability to do completely good acts or completely bad acts. This gives them the option to do either and they set thier adjenda.
However, you seem to want it both ways. You want Good to be defined so that when a person does it you can recognize it - but for it to be subjective - so that when you choose to argue against what you do (i.e. eat meat) you can. You can only do this is you remove intent of the being. Once you remove that - we do not have enough evidence to even discuss Good or Evil (atleast when concerning human actions). If an animal has the intent of torture for no purpose - it actions are evil or bad (but how often have you seen that in the animal world as in comparison to the human world). We torture while we prepare our food because we do not care - and that makes our actions evil.
4) You say 'respect has no place in the consuption of food'. Odd, that only in a country where there is way more food than we need and over 50% of us are obese that we could say that. The rest of the world that does not have enough large protien souces to consume respects the hell out of thier food when they get some to eat - but this leads me back to my original comment - you are making economical observations - and smuggling in your ethical comments.
Ethics asks not what is going on or what could be going on - it asks what aught we do. Sure in our economy we could simply torture all our animals before we eat them and gain some efficiency, which is what we do - but it doesn't de facto make it ethical.
I do respect the food that I eat because I work my butt off to buy it and provide my family with it. I do not waste much and I hate to see people who do. However, your argument is that because vegans are eating vegetables (which is killing) I should be able to eat anything I want in any method I want. Let me give you a similar argument. You eat steaks. They are made of animals. I should be able to make steaks out of you because you are an animal I can make steaks out of. The argument of yours sounds as silly as the one I have just proposed.
The question is not necessarily what do we do - but what aught or could we do to be more humane.
