The history of the World Trade Center is a case study in why government should not be involved in private-sector development.
"...From the moment it opened its doors in the early 1970s, the center, owned and operated by the publicly funded Port Authority of New York and New Jersey, was really a grandiose monument to the ills of state capitalism, where government substitutes its bureaucratic and politically motivated thinking for the wisdom of the free market's invisible hand. Indeed, the WTC offers a case study in why government should not be in the business of developing and managing commercial property. As New York state and city officials move toward setting up a new public entity to oversee the rebuilding of lower Manhattan, the center's history provides a cautionary tale for everyone involvedstarting with Governor George Pataki."
