No. You come off it! Your complaint is feverish and irrational. Whether or not a station or area is adequately served or "over-served" revolves essentially around the ratio between the number of passengers and the amount of transport provision. Your low opinion of the area and its residents is irrelevant. Stratford is in a densely populated part of inner London and is a major passenger interchange station. Consequently the number of passengers using Stratford is extremely high and the transport provision needs to be correspondingly high.

Your belief that the Jubilee Line trains have been crowded only since the opening of Westfield shows how little you know about the Jubilee Line and Stratford.

Your reference to Cockfosters, Barnet, Stanmore and Edgeware is completely beside the point. Those four places have no alternative rail transport. Thamesmead will be part of the Cross Rail system and has Abbey Wood and Plumstead stations nearby already. Not taking the Jubilee Line to Thamesmead did not mean the area would be without rail transport. Your comparison is not valid.
