The "taxpayer burden" is probably the dumbest argument in this whole issue. If
you fall out of your boat and drown it is probably the cheapest way for you to
die from a tax burden standpoint. Certainly a lot cheaper than the typical
10-15 years of illness that constitutes "natural causes".
People drowning before they reach 61.5 is probably the optimal situation if you
are really worried about the poor taxpayer. You paid into FICA/Medicare for 40+
years and didn't take a dime.
