UK and Australia are the test beds. US is the target. From there it flows onwards and outwards. Like raw sewage over the Niagara Falls.
The AU my.health opt-out debacle[1] is similar. UK got in first, promised they wouldn’t sell the data then did so. AU then started by copying the UK’s best practice. So... fun times ahead.
They’re still trying to get the gun laws fit for size in the US but the political climate and history is too different. And the attempt on the health system via Obamacare didn’t quite take either. More time needed apparently.
