A very small minority of any population is ever wholly dependent on their government for money and healthcare.
So thats a minority argument but lets for arguments sake
unpack it and see where it leads.
So the crux of your position is you not being RESPONSIBLE for the poor life choices of others. 100 percent agree. You are NOT responsible for others wrong, bad, negligent, irresponsible choices.
You are both right ... many illnesses and life scenarios are the direct result of an individuals actions or inactions.
You believe Medicare is not your responsibility.. ok I get that sentiment. But youre not Medicare. Yes the government is, for want of a better descriptor.
You claim to be concerned about aborting foetuses .. are you concerned about aborting foetuses with congenital defects? If a person cannot afford to care for a child with high medical needs ... who can? Who will?
Would you assist an individual to raise a child with high medical dependencies? To save that child from abortion?
What about illnesses that are NOT caused by inaction or action? What about non causative cancer, like Leukaemia, breast cancer, prostrate cancer, you cannot blame a persons life choices for getting cancer. What about leprosy, the flu, tuberculosis, Parkinsons, Muscular dystrophy or MS?
My point, in case its lost on you ... is that not all illness is a result of a human action.
Those that are, there is a compelling argument that they ought not be covered under a public health system like Medicare.
However, is it not in the nations interest for a people to be educated and healthy? Is it not in the interests of broader public health?
My perspective is different to yours ... I see that personal individual responsibility is a positive but I also see that there are those that are struck down with diseases, health conditions that they could literally not, through any actions of their own avoid.
