Not everything we can do is something we should do but who decides?
We are not the only country that can treat lukemia or or other such things now we are only the most expensive place on the planet to get such care. That is the problem. We seem to have too many hogs at the trough and too much greed. The system is free to charge what the traffic will bear and does.
If you can identify anyone who can be fired without affecting the quality or timeliness of healthcare, then I am in favor of getting rid of them. But I am not sure how much of a dent you can make that way. Our standards are very high. The last few times I visited a hospital, the people were in private rooms. That seems to be the norm now. In a lot of places you are on a ward with a bunch of other people. There has to be a cost to that. In Canada, you can wait a very long time for some procedures. If someone needs something right now and they have no capacity, they send them to - guess where? The United States. We are literally the relief valve for their system. If we go their way, who is going to pick up our slack?
At least we are not yet in the same boat as the UK. People who have been waiting in line forever for some procedure are being pushed back even further to make room in front of them for illegal immigrants.
