Why should government be involved in health care?

The question of government involvement in Healthcare for Canadians, is never asked during a political debate or during and election campaign.
It is the "elephant in the room," that no politician wants to acknowledge because doing so will make him/her unelectable. So to be elected, the proper approach to take is to agree, yes health care has some problems, but throwing more money at it while eliminating wasteful practices will fix the problems and everything will be wonderful in the future. But the plain facts in Ontario's current election are, that the health care budget will become the largest component of the budget and health care will not improve because demands on it will only increase from here on in.
What's the solution? Clearly something needs to be done, and this video excerpt points to a new beginning.
