This is hardly the only country where the big teams get the big decisions. Every league in the world suffers from this. In fact, after we were relegated, we were the 'big' team in the First Division and received more than a few favourable decisions ourselves.
If we did go down the video technology route, it should only be for very specific cases and I'd like to see it follow the American football approach i.e. the officials make the call on the field and it can only be changed if the video evidence shows irrefutable proof that the decision was wrong. If there is any doubt, then the decision on the pitch stands.
The big problem is, of course, that games like American Football have far superior coverage with their multiple cameras. In situations like offside, unless the camera is exactly in line with the players in question, the angles can be easily skewed and make it difficult or impossible to get an accurate read.
