While the detail of the route system is important, a key difference between NY/LA Tracon and London is that in the US the system is designed to allow lots of high density airports to launch and receive IFR traffic and still have substantial VFR capacity whereas the system in the London TMA has relatively little capacity to deal with VFR/pop up traffic.

There are several factors. The most important is probably the design and regulatory philosphies. Others are that 'everything' in the US costs less, that there is one integrated service provider (vs. the European segmentation). While London/UK should have local scale economy over the average of the US, the US certainly has scale economy over Europe. The UK shouldn't be 'complex' relative to NY/LA, although from published data I can't tell if NY/LA benefit from scale (so have a low cost per IFR flight) or are adversely impacted by complexity (so have higher than average costs)
