yes representative democracy deals with this problem in a way that workers councils doesn’t. swarms of lobbyists (not evil) and aides are not industrial workers
It seems that you aren't familiar with the meaning of words that you are using. Workers councils are made up of delegates that are voted on by the workers i.e. they are a representative democracy.
I would expect that they would be more effective at advancing it's electorates interest than the owners would be at advancing their workers interests for the simple reason that the new elected body can be simply removed and a new one voted in.
Did anybody say there was anything magical about workers? Since you are asking this question you must think that there is something magical about owners so why don't you tell us about that first?
