America has fiber and mostly copper (from our phone line laying days) strung all throughout America, the bandwidth is much higher in total.

The job left here is replacing copper w/ fiber (or at least DOCSIS 3.1 via copper), but it's expensive and some ISPs it isn't worth it for the customers they have, so you have some areas bringing the national average down.

Starlink will be nice for really remote areas where it make no sense to run a line or a tower for a couple customers. Existing sat internet is unusable. There's also been a big push to modernize slightly bigger towns with fiber by smaller ISPs.
