It certainly does, from the demise of the 1,600 opera houses in Iowa--to
health care--to the elderly--to education-- to the new "for-profit Star
System"--to the demise of the "not-for-profit" public service area in the
new flat tax proposals from both parties in Congress--to the coming
integration of several million out of work angry workers into a private
sector that doesn't have room for the workers they have. Sounds like a
recipe for:

"connectivity rapidly disentegrating, leaving a dispersed
'archipelago' of relatively small sub-communities."

i.e. you can only trust your relatives. Maybe like Bosnia? Is there
something about American culture or business that makes us keep making
this mistake? Maybe a rebel gene?
