I've been living in the US for 10+ years so I'm not very well informed, but basically the ISP industry ended up in an oligopoly where everybody's friends with the government, and they kept raising prices while neglecting infra upgrade. Until nobody can call Korea's internet "fast" any more.
Now all we've got is shitty websites. (To be fair, they are somewhat less shitty now... you can now access your banking websites on Mac!)
