Let's say you are right in your evaluation (mind you there are non-biased animal activist who are reasonable argue differently) why isn't this still a viable business model? Why aren't small business owners still advocating this service.

Let's use logic here (not saying you aren't). Yes, politicians can do more harm than good but they wouldn't push policies that causes people to lose jobs.

Also, you can coerce a 1800 lbs. animal to do something which was one of the video shown to me which changed my mind about the practice.
