What is the wholesale price? Is the same for everyone?

In the UK the line is reasonably priced (wholesale around US$15/month
for FTTC, FTTP is rare and $25 to $80/month) but backhaul is a problem
as the incumbent charges around $40/ Mb/s /month.

You're not going to sell a service with that for a viable price
when retail prices are around $20/month for the popular products (40
and 80Mb/s). It skews the market to a hand full of large providers
who can afford to build their own backhaul

On the FTTH I've been involved in ( I used
AE rather than GPON.

Positive factors were:
Simple, cheaper, CPE not needing replacing each time a new faster
wifi standard appears (the service is 1Gb/s).
Simpler build with dispersed properties.
Preference to maintain a (cheaper) ethernet switch vs propriertary GPON
Any business can be given dedicated 1G DIA and can independently upgrade
to 10G.
With a lot of farms/home working the business/domestic distinction
is fluid.

Higher fibre costs but not huge vs GPON kit.
A fibre cut results in a lot more fibres to splice increasing
time to repair (96c on our trunks, would be 12c with GPON). This
is the only major AE issue.
