Very interesting article that just landed in my email from Digg.com:

One interesting quote 
"We deregulated high-speed internet access 10 years ago and since then we've seen enormous consolidation and monopolies… Left to their own devices, companies that supply internet access will charge high prices, because they face neither competition nor oversight."
Take a read. A lot more researched and probably more valid conjecture than you will find here on an RV message board.
