That sounds reasonable? If I'm an end-user, what I'm paying my ISP for is to get me data from Netflix (or youtube or wikipedia or ...); that is the whole point of having an ISP. If that means they need to run extra links to Netflix, then tough; that's what I'm paying them for.
You're paying them for access to the ISPs network. For an internet connection, this also comes with access to other networks through your ISPs peering and transit connections.
If you know of any ISP that would give me 100+ Gbps connectivity for my business, please let me know as I'd love to eliminate my bandwidth costs.
