You guys don't actually know the worst of it , in former warsaw pact countries there are 3 types of horse people
There are the rich - horses are for the most well looked after , and have lives that wouldn't be much different from that of western countries
There are Pesants ( not joking ) -again horses for these people are for the most well looked after - or as best as they can, they are not abused but are a means of transport and money, mares are preferable as they can produce a foal every year that can be sold for meat. What would be seen as abuse in the eyes of westerners is just either a matter of ignorance or a lack of money, tack is often poor , scraped together from whatever they can find and very old. The horses are worked until they are either too old or have an injury that cannot be fixed - they can't afford vets - and then the animal is again sold for meat.
And then there are - lets call them ........ - these people will look all over the country for horses that no one else wants, young horses , geldings , problem horses , meat horses etc. They will subject the horses to a very short , rough handling methods that do one of two things, the horse will be ' broken in spirit ' and become docile ( one way of thinking is that the horse shoulld be so scared that it dare not mess about ) , the horse is then sold onto the pesants or to stupid rich people .
If a horse behaves in the manner in this video it will probably end up as salami by the end of the week as these people have no time to train it properly.
Sorry to be blunt but that is how it is over here - I am speaking from first hand experiance. I am not saying that all people from eastern block countries abuse horses, many love their horses the same way that you do - Hungary, where I live, has a long history of being a horse nation but there are still people here that are not Magyars ( proper hungarians ) who are for the most part responsible for most of the abusive behavior.
