The debt is not really the problems.. All those telecom executives just don't know what assets to buy. When they listen to WS and bought outdated assets that is not able to grow revenue but only endless CapEx, that is what happened..
That is the sad things about telecoms... Whole bunch of managements from every companies, total incompetent for new internet area. Don't even know what is going on.. I wonder do they even go to attend MSFT/AMZN/GOOOG or any high-tech sale conference.. Just hard to believe...
