However as things stand the 20% of customers grabbing 80% of the network will also grab 80% of this increased capacity, so they are being even more heavily cross-subsidised. Clearly cross-subsidy is always going to happen to an extent so long as you have flat fees for access (even if you put in tiered fees, there is still cross-subsidy). But this should not be excessive else customers suffer.

Please cite evidence to support this assertion. At least for the ISPs I have worked with & for the margins are pretty thin and while Transit/Peering costs are not the largest cost they are not insignificant. We saw large scale "streaming events", e.g. day long sports event broadcast on the Internet, had significant (localised) impact to the Transit costs and if they were permanent (e.g. your average 1 Mbps / user at peak time) they would have made a significant impact to the bottom-line.
