Do you think that it is mathematically impossible for the federal
government of a country to stop at least the vast majority of this
stoppable suffering and premature death caused by lack of proper food,
proper shelter, and proper health care?

I think it is mathematically impossible for this particular federal government of this particular country to do so, yes.  Not in its present frame of mind.

Your analysis is freakishly devoid of compassion for all the tax boycotting US armed services veterans who ask their civilian contemporaries to stop feeding the monster.

You paint your opposition in monochrome as "conservatives" who won't bow to your superior Krugmanesque crapola.

You hold up the image of poor families and singles needing health care and want us to think big government is compassionate.  

That's bait and switch.  They money to take care of those people has already been provided, many times over, if you subtract the unnecessary wars.

The unnecessary deaths have been multiplied many times over if you factor in what was really done with that money.

I'm sitting here in a Quaker meetinghouse right now, listening to veterans who've gathered this Armistice Day (aka Veterans Day) to discuss their feelings of betrayal.

The US Navy woman assured us her ship in the Gulf was doing nothing whatsoever to address "911".  It was about testing the equipment, the munitions, a giant war game.

These vets do not want to be "thanked".  They want civilians to hear what their saying.

Yes, the American people definitely need better health care.  

If they ever get a legitimate / honorable government, maybe they'll get some.  

In the meantime, I have to say I'm horrified by your one string harp way of answering these challenges.  

You barely pass the Turing Test in my book.
