We are normally not asked to die for our political leaders, at least not that I am aware of.
As for disparities between have and have not. I agree that this is an issue of real concern as it taxation, health care, education, I include the arts here, and many other social issues. Over the years Canada has improved and enhanced many of its social programmes so that more and more people are covered by them. Is it enough, propably not but these are complex issues and throwing money at them or reminding people that Mr. Harper has never been to a food bank does not cast any great light on the issue. That approach is mere darkness Visible.
   Generally, I think people are far more tired of ill informed skeptics than they are of politicians.
    If we are truly dedicated to improving the lot of our fellow citizens we must first inform ourselves as to the real issues..then, and only then, can we insist that our political leaders lead us, not follow us, to where we wish to go.
