There are LOTS of differences between there and here. I have been to Japan and South Korea. I will explain why is vastly different there as opposed to the US.
But 1st.
1. I got the same letter from comcast. If you read the small print at the bottom of the page (at least in the letter I got (I live in MASS) there was a little footnote at the bottom of the page that said, to get 4 mps, it was an extrs $10 a month)
2. Here in Mass Verizon is installing a 30 mps DSL network in the boston and surrounding towns area. It will be ready to go in about 4-6 months.
Now onto South Korea.
South Korea -
A. Size. South Korea is about the size New England, probably a little smaller. All the large cities are near each other. Imagine trying to run fiber optic cable from New York to LA. Its not cost effective. It was much eaiser for them to wire the country than it would be for us. Also, they major cities are far more jam packed, and close together.
B. Goverment funding. Its not a capitalist society over there. The goverment was able to control, fund, and regulate the market and invest large sums of money to wire the nation.
C. Timing. Most cable in the US got laid in the 70's and early 80's. Broadband was not a thought on the radar. South Korea, most cable was laid in the 90's. Broadband was already thought of, and high speed fiber was laid to START with.
D. Income. Avg income there is about 60% of the US. Its all about what the market can bare. If they were to price it at $50 or more, no one would be able to afford it. But with goverment funding, handling the initial cost of laying the fiber and installing, companies dont have to recoup that start up costs.
So comparing us to them, without the facts, doesn't give a clear picture.
