Also most people in the west don't worry about overloading their home's electrical supply by connecting too many devices. That is equivalent to a gigabit connection. A 100Mbit connection would be equivent to maybe a 4kW home supply in a temperate climate - probably enough for the average user but only just you'd still have to watch your usage. Additionally the real benefit to FTTH is not bandwidth but ping which is noticeable. And no sane operator is installing FTTH with sub-gigabit capacity because it's a complete waste of time and money.
