Who is suggesting that people should be working harder?Yes, damn those junior doctors, only working up 90 or 100 hours per week including >24 hour shifts. If only they'd work a bit harder, we could clear all those waiting lists so easily.
There are structural issues within the health service which causes massive duplication of process which results in massive waste. Lack of labour flexibility means that people can't be moved to different tasks so one area can be under staffed while another is over staffed. This also causes massive waste. That doesn't mean people are slackers.
