Baseball is the same. Tradition over technology.
Yeah, it's the worst officiated sport I can think of.
I think they should add two more linesmen, and make discussion/collaborative-decision making between the ref and his assistants more common practice like it is in baseball and American football. The official time-keeper needs to be someone who is NOT a referee, and YES, as you said they need to figure out a way to incorporate video instant replay for controversial/dispute calls-- but do it in such a way that it doesn't add too much time to the game (that's always been the challenge with introducing it in American sports).

It's NOT the same
1. The head umpire does not have nearly as much power as a soccer ref
2. Umpires regularly review calls with each other collectively if an ump second guesses himself or another ump saw something different.
3. Baseball did experiment with instant replay technology at one point, but concluded it just ended up adding way too much time to the games, which are already the longest in American sports by far.
