it is also money, lots of these super fast countries the networks are being built by state owned or state funded telecoms and not stock held corporations.
could our corporations run fiber to every home, sure but the stock holders would fire the board.
No they're not. Japan didn't subsidize fiber build-out. They used very strict regulations to encourage FTTH. That's why their most remote rural areas still don't have fiber.
Sweden is the same. Only South Korea's government really seems focused on subsidizing fiber build-outs.
And considering the telecoms received $200 billion here in the US to build out fiber (and instead used that money to build their wireless networks, which have been a giant cashcow for them over the last 10 years), I don't see how the industry could be any more "subsidized" over here.
