If this is a serious statement, then you have clearly been affected by the propaganda that is put out by your country's for profit healthcare system and their lobbyists. They make great efforts to paint any system other than theirs as being substandard with talk of "death panels" here and nonsense like that.
Our system here is far from perfect, and could have many improvements certainly, but we spend less per capita than the US, have better overall outcomes (as do the majority of single payer systems, of which ours is one of the worst performing unfortunately), we have greater life expectancy, lower infant mortality rates, etc.
From the perspective of someone who is a regular user of the system here, have I ever waited 4-6 months for an appointment?
From my GP? Nope.
From my dermatologist? Nope.
From my rheumatologist? Nope.
From my cardiologist? Nope.
From my physiotherapist? Nope.
From any other medical practitioner? Nope.
So they either somehow know months before I do that I need the appointments and have pre-booked me even before I call, or the idea that this is the norm here is complete nonsense. I think I know which is more likely.
