Well said runway30. I was in Telecoms for 27 years including throughout deregulation. Some made a fortune, most did not. By about 2010 it was all over. The small fry had been swallowed up by the big boys. The raft of new jobs that new technology provided, drifted away as the technology matured and no longer required skilled engineers and constant, on site monitoring.
Rather like the fallout from deregulation of airlines.
