I wish we had a system like South Korea.
A single entity owns, operates and maintains a single country-wide WAN. It leases nodes to ISP's. The more nodes, the more bandwidth. So not only does this open a healthy competitive market, but also allows the operation of ISP's which focus on a certain customer base. An ISP could focus on customers who would use bandwidth for emailing the grandkids and checking on their retirement investment. Low bandwidth for a very low price.
All this is what gives South Korea the recognition of fastest internet speeds. A healthy competitive market with many ISPs all vying to find that fine line of a healthy profit margin and lowest cost to highest bandwidth ratio to attract the most customers.
